Last week when I sharedThe top programming languages that will be mostpopular in 2017, the frequent comment was, what does it take to be a better developer?

I’ve met some amazing developers in real life and through React Native Community, and I decided to ask them, “How do I become a better developer?” Thank you to everyone who took the time to answer these questions with passion!

This is a compilation of answers I received from them. Some of these quotes are not limited to answers from that specific question.

Q&A

Aravind Kumaraguru

Aravind is an undergrad at UC Berkeley pursuing a degree in Electrical Engineering and Computer Science and is Engineering Director for the nonprofit organization Pioneers in Engineering.

Q: How do you think I can become a better developer?

A: Obviously, never stay complacent with what you know – this field changes ridiculously fast, and you need to keep up with it. Follow along with the news in the tech industry, perhaps read up on some source code for a Python module that you recently used.

A friend of mine had some free time over winter break, so he decided to teach himself Django and build a webapp that he could interact with over SMS. It’s sort of a toy project, but he really enjoyed learning the different development paradigms. For context, he specializes in embedded systems and robotics, so this is nowhere near his comfort zone.

But pushing yourself to try different things will make you much stronger as an engineer. I personally wish I had done more web stuff before this year – in my organization (PiE), we’re developing a new iteration of a robotics kit to be used by high school students. While I have a good grasp of the low-level and systems stuff, I’m at a loss when it comes managing our UI design. Never had an interest in doing that type of stuff full-time, but having even a surface-level knowledge can be immensely helpful

Q: Do you have any projects you did to push yourself out of your comfort zone?

A: I built an automated door opener last summer, which operated a mechanical lever to open a door when an RFID card was scanned. The project used a really powerful motor and a mess of sensors to track the state of the arm, which proved to be quite difficult to coordinate. I learned real quick that I would need to do a bunch of offline testing before running my code on the device, which was very different from what I was used to up till then.

In terms of academics, I just finished CS 189, which was a massive crash course in data science, optimization, and probability theory. The programming I did in that class was also very different from what I’m used to, even though it was all in Python.


Brent Vatne

Brent is Front-end web/mobile developer working on Exponent and React Native. He contributes to tons of open-source projects.

Q: I really want to become a better developer; what would you say the first step is?

A: Do stuff you’re excited about and contribute to open source projects:-D

Q: How old are you and how much experience do you have as a programmer?

A: I am 30 years old, and very much 😮

Q: How did you join Exponent? What was the cause?

A: James (ide) and I were the most active contributors to a react-native outside of facebook and so we spoke a lot. He created exponent with Charlie. I ended up doing some consulting work with them and Charlie asked if I’d be interested in working with them full time and year, it was lots of fun so I joined.

Q: I should know objective C and Java thoroughly before I jump into React Native, right?

A: You can learn it as you go if you need to. there’s also tons of pure javascript stuff that need to be done. and documentation. lots of things 🙂


Charlie Cheever

Charlie Cheever is the co-founder of Quora, an online knowledge market. He was formerly an engineer and manager at Facebook, where he oversaw the creation of Facebook Connect and the Facebook Platform. Prior to Facebook, Cheever was employed by Amazon.com in Seattle. He left Facebook to start Quora in June 2009 to work on Exponent.

Q: What’s the motivation of Exponent being free and Open Source?

A: I really want to make something that like a 12-year-old version of me would use. So, someone who doesn’t know tons about programming but can learn new things and doesn’t have a credit card or lots of money, but has time and creativity and a phone and friends. I learned to program making calculator games on TI-85, it’s sad to me that kids can’t make stuff on their phones today.

Q: Why did you leave Quora?

A: I managed the mobile teams there and it was so slow to work on those apps even tho we had good people, I found it so frustrating And after I left I tried to build some mobile stuff and it was so annoying that I decided there needed to be a different way to make stuff. So James and I made something like react Native called Ion. It was strikingly similar actually. But React Native already had android support and 20 people working on it, and we had 2 people. So we decided to make everything else around it that we wanted to make!

Q: What did you do on Facebook?

A: I made the developer platform that all those games like FarmVille were on. Well, not all of it obviously but was one of two main developers. And I worked on the first version of facebook video, then did a lot of random other things. Then was a manager and did log in with Facebook on other sites, and then left to do Quora.

How to monetize your programming skills


Christopher Chedeau

Christopher has been working at Facebook as a Front-end Engineer for about 5 years. Previously, he worked at Curse Network.

Q: What do you do on Facebook?

A: I was on the photos team when I started, then I discovered React and started adopting and promoting it both internally and externally. I was there at the beginning of reacting native and pushed it through until 3 months ago. I just recently switched to the Nuclide team. I’m still #3 contributor on React Native.😛

Q: Do you have any prior work experience?

A: I was working for Curse (doing website for blizzard games) during my college to pay for it. It was fun to see the company go from 5 people in a guild to a 100 people company.

Q: What’s your day to day like on Facebook? The current project you’re working on?

A: I’m currently working on the Nuclide team, Facebook’s IDE built on top of Atom. I would say my time is spent half coding, half cheerleading all the cool stuff people are doing inside of FB.

Q: How do you think one can become a better developer?

A: I think that there are multiple levels.

The first level is mastering all the concepts. For example yesterday I had to write a function that removes certain keys from a big nested object. Because I’ve done this task so many times in the past, I was able to implement it in one go without even thinking and it worked the first time. For this one, exercises are really good. You want to code the same kind of things many many times to train your muscle memory.

The second level is how do you build things in a way that are not going to break in the future. Ideally, once you build something, you can move to the next thing and it’ll keep working without you there. This is challenging when there’s a ton of developers touching the codebase and product directions changing often.

Finally, the third level is how do you prevent a whole class of problems from even existing in the first place. A good example is with manual dom mutations, it’s very easy to trigger some code that interacts with a dom node that has been removed from the dom. React came in and made this problem go away. You have to go out of your way to do so, and even if you want to do those things, you have the tools to make it work: lifecycle events.

Q: Is there something you wish you’d known or learned earlier as a programmer?

A: Probably the most important thing is: tradeoffs, tradeoffs, tradeoffs. They are everywhere.

If you are working on some random throwaway feature that no one is going to use, who cares if the code is maintainable, you need it to work and now one mistake I see a lot is that people over-engineer the easy things but are not willing to make their architecture less clean from a CS perspective even though it actually provides the user experience you need.

At the end of the day, we write all this code for the users, we should first understand what the user experience should be and then do whatever it takes to get it. If the user just needs to display some content and needs to be able to edit it easily, just install WordPress, pick a good looking theme and call it a day

– Btw, pro-tip, if you want to be successful, always think about the value you are providing. If you are earning $100k a year, this means that the company should be making $200k because you’re here


Dan Horrigan

Dan is a Senior Back-end developer @Futuri Media. He has 20 years of programming experience in many different languages. He’s been contributing to React Native early/mid-2015.

Q: What’s your background as a programmer?

A: I started learning to program (with QBasic) when I was 11 and was hooked. I learned everything I could, as fast as I could. I learned a few languages like Visual Basic and started to dabble with C and C++. Then I found web development and dove in head first. First, learning HTML and CSS, then adding simple CGI scripts written in Perl, and eventually Classic ASP.

My first paying project was when I was 14: A website for the company my dad worked for, with a customer portal to let them see their job progress. This was all in ASP. After that, I started learning PHP, and have been using that as my language of choice ever since. However, I picked up a lot of experience with other languages along the way: JS, Python, Ruby (on Rails), Java, C#, Go, Objective-C.

Q: What are some projects you’re currently working on?

A: I work for Future Media (http://futurimedia.com). We provide SaaS solutions for Broadcast Radio and TV companies. We provide white label mobile applications, social engagement and discovery, audio streaming and podcast solutions, etc. I haven’t had much free time lately to contribute to many OSS projects, but hope to change that soon!

Currently, I am a Senior Back-End Web Developer, but I am transitioning into being the Director of Technical Operations.

Q: Is there something you wish you’d learned or knew earlier as a developer?

A: I wished I would have realized earlier in my career that it is OK to be wrong, and that failure is just a chance to learn.

Q: What’s the first step to becoming a good developer?

A: Come up with a small-ish project that you think would be cool, or would make your life easier, and just jump right in. Too many people try to learn without a goal other than “I want to learn to code.” Without a goal, you are just reading docs or copy/pasting from tutorials…you can’t learn that way.

To become a better developer, you need to do one simple thing: Never. Stop. Learning. Read other people’s code, figure out how that one app does that really cool thing you saw, read blogs, etc. No matter how good you are, or think you are, there is always someone better, and always more to learn.

Q: Is there a certain project you’re currently interested in? Next on your learning list?

A: I have been using, and occasionally contributing to, React Native since early/mid-2015, and continue to be interested in it.

Next, on my learning list is learning Erlang/Elixir. We build heavily distributed systems where I work and think we would really benefit from a language like that.


Frank W. Zammetti

Frank is a lead architect for BNY Mellon by day and the author of eight books on various programming topics for Apress by night

Q: How do I become a better developer?

A: I get asked this question quite a bit both at work from junior developers and from readers of my books. I always give the same answer: make games!

It sounds like a joke answer, but it most definitely is not! Games have a unique ability to touch on so many software engineering topics that you can’t help but learn things from the experience. Whether it’s choosing proper data structures and algorithms, or writing optimized code (without getting lost in micro-optimizations – at least too soon), or various forms of AI, it’s all stuff that is more broadly applicable outside of games. You frequently deal with network coding, obviously audio and visual coding (which tends to open your mind to mathematical concepts you otherwise might not be), efficient I/O and of course overall architecture, which has to be clean and efficient in games (and for many games, extensible). All those topics and more are things that come into play (hehe) when making games.

It also teaches you debugging and defensive programming techniques extremely well because one thing people don’t accept in games is errors. It’s kind of ironic actually: people will deal with some degree of imperfection in their banking website but show a single glitch in a game and they hate it! You have no choice but to write solid code in a game and you figure out what works and what doesn’t, how to recover from unexpected conditions, how to spot edge cases, all of that. It all comes into play and those are skills that developers need generally and which I find are most frequently lacking in many developers.

It doesn’t matter one bit if the game you produce is any good, or whether anyone else ever even plays it. It doesn’t matter if it’s web-based (even if your day job is), or mobile, doesn’t matter what technologies you use. The type of insight and problem-solving skills you build and tune when creating games will serve you well no matter what your day job is, even in ways that are far from obvious.

I’ve been programming games for the better part of 35 years now. No, none of them have been best-sellers or won awards or anything like that. In fact, it’s a safe bet that most people wouldn’t have even heard of my games, even the one’s still available today. None of that matters because the experience of building them is far and away the most rewarding part of it. Perhaps the best thing about programming games is that they are, by their nature, fun! You’re creating something that’s intended to be enjoyable so the process of creating it should absolutely be just as enjoyable. How many things can you do that are really fun while still being challenging and simultaneously help build the skills needed for a long career?

So yeah, make games, that’s my simple two-word answer!

Q: Is there something you wish you’d known or learned earlier as a programmer?

A: Hmm, tough question actually. I guess if there was one thing (and I’ll cheat and combine two things here because they’re related) I would say that early on I didn’t understand two very important phrases: “As simple as possible, but no simpler” and “Don’t let the perfect be the enemy of the good”.

I have a natural perfectionist mentality, so I spend a lot of time pondering architecture, API design, etc. I once spent 33 hours straight working on a Commodore 64 demo because ONE lousy pixel was out of place and my perfectionist brain just couldn’t live with it! Sometimes, I have to force myself to say “okay, it’s good enough, you’ve planned enough, now get to work and actually BUILD stuff and refactor it later if needed”, or I have to force myself to say “okay, it basically does what it’s supposed to, it doesn’t need to be absolutely flawless because nobody but me is even going to notice”. Especially when you’ve got deadlines and people relying on you, you have to make sure you’re working towards concrete goals and not constantly getting stuck trying to achieve perfection because you rarely are going to, at least initially anyway, no matter how hard you plan or try – and the dirty little secret in IT is that perfection rarely matters anyway! Good enough is frequently, err, good enough 🙂

And, your design/development approach should always strive to be as absolutely simple as possible. Of course, what constitutes “simple” is debatable and doesn’t necessarily even always have the same meaning from project to project, but for me some key metrics are how many dependencies I have (web development today is a NIGHTMARE in this regard – less is GENERALLY better) and how many layers of abstraction there are. Developers, especially in the Java world, like to abstract everything and they do so under the assumption that it’s more flexible. But if there’s one thing I’ve learned over the years it’s that the way to write flexible code is to write simple code. It’s better than abstractions and extension points and that sort of stuff because it’s just far easier to understand the consequences of your changes.

As a corollary, a terse code is NOT simpler code! Simple code is code that anyone can quickly understand, even less capable developers, and even yourself years after. Terse and “clever” code tends to be the exact opposite. Often times, the more verbose code is actually simpler because there are fewer assumptions and often less knowledge needed to understand it, less “code hoping” you have to do to follow things. Related to this is that writing less code isn’t AUTOMATICALLY better. No, you shouldn’t re-invent the wheel, but you also shouldn’t be AFRAID to invent a marginally better the wheel when it makes sense. Knowing the difference is hard of course and comes from experience, but if you think it’s ALWAYS better to write less code then you’re going to make your life harder in the long run.

Of course, don’t over-simplify code either. Too simple and suddenly extending it almost MUST mean a refactor. You never want to completely refactor because you HAVE to in order to build an app over time. There’s a balance that’s difficult to strike but it should always be the goal.

Oh yeah, and I wish I knew how to express myself in fewer words… but actually, I’m still obviously working on that one 🙂


Janic Duplessis

Janic is the co-founder of App & Flow, a react-native contributor, and open-source contributor.

Q: Any tips to becoming a better developer?

A: Don’t think there’s anything in particular, you just have keep learning and getting out of your comfort zone. Like trying a new language or framework from time to time. At least that’s what I do but I’m pretty sure there are some other good ways haha 🙂

Q: How can I start contributing to React Native?

A: The best is to start with something small like a bug fix or adding a small feature like an extra prop on a component. Most contributors know either iOS or Android and a bit of JS. There are also some JS devs that work on things like the package and clip. We keep some issues with a Good First Task label that should be a good place to start


Jake Murzy

Jake is an Open-source Archaeologist. He writes buzzword compliant code. Co-founder at @commitocracy.

Q: Hey Jake, any tips to becoming a better programmer? 🙂

A: Number one thing you should do is to learn your tools before you learn the language you work in because it will lead to faster feedback loops and you will get to experience more in less time. So install a linter and it will catch most of your errors as you type. It statically analyzes your code and recommends best practices to follow. You should always follow best practices until you gain enough experience to start questioning them.


Jun Ho Hwang

Jun is a software engineer at Coupang, which is the $5 Billion Startup Filling Amazon’s Void In South Korea. He is a very friendly developer who loves to connect.

Q: How do you become a better developer?

A: The word ‘better’ can be described in various ways–especially in the field of programming. A good developer could be someone who is exceptionally talented in development, someone who is amazing at communicating, or someone who understands Business very well. I personally think a “good” developer is someone who is in the middle–a person who can solve his or her business problem with their development skills, and communicate with others about the issue. Ultimately, to achieve this, it requires a lot of practice, and I recommend you to create your own service. Looking and thinking from the perspective of the user and improving the service to fulfill their needs really helps you grow as a better developer.

Q: Is there something you wish you’d known or learned earlier as a developer?

A: I really wish I started my own service earlier on. The hardest thing to grasp before developing is realizing how you can apply what you learned. Many developers are afraid to start a “service” because it sounds difficult; however, pondering about what to make and where to start, and then connecting those points of thought help you grow as a better developer.

Q: What do you do at Coupang? What are you currently working on?

A: Coupling provides a rocket-delivery-service, and I am working on developing a system called “Coupling Car,” which is related to insurance and monetary management. Furthermore, I’m thinking about adding transportation control system and the ability to analyze data from the log.


Keon Kim

Keon is a student at NYU who is really passionate about Machine Learning. He is a very active GitHub member who tries to contribute to open source projects related to machine learning.

Q: What are your interests? What kind of projects have you worked on?

A: I’ve been working on machine learning projects these days. I am one of the project members of DeepCoding Project, a project with a goal of translating written English to the source code. I’ve been contributing to a C++ machine learning framework called my pack(https://github.com/mlpack/mlpack), which is equivalent to skit-learn in Python.

I’ve also done some fun side projects: DeepStock (https://github.com/keonkim/deepstock) project is an attempt to predict the stock market trends by analyzing daily news headlines. CodeGAN (https://github.com/keonkim/CodeGAN) is a source code generator that uses one of the new deep learning methods called SeqGAN.

Q: How do you become a better developer?

A: I think it is really important to understand the basics. By basics, I mean math, data structures, and algorithms. Deep learning is really hot right now, and I see people jumping into learning it without basic knowledge in computer science and mathematics. And of course, most of them give up as soon as mathematical notations appear in the tutorial. I know this because I was one of them and it took me really long time to understand some concepts that students with a strong fundamentals could understand in a fraction of the time I spent. New languages, libraries, and frameworks are introduced literally every day these days, and you need the fundamentals in order to keep up with them.


Munseok Oh

Munseok is a Full-stack developer and CTO at Sketchware. He previously worked at System Integration for ~7 years.

Q: How do I become a better developer?

A: When I was very young and cocky, I evaluated other developers based on their coding style. There were certain criteria they had to pass in order for me to judge them as a good developer. But now, I really don’t think that way. Now, I believe that every developer is progressive, which means he or she is becoming a better developer every day. It doesn’t really matter if the style is bad or code is good–as long as the program runs, I think it’s great! Whether the program has room for growth or has bugs, I think the motivation to develop is what really matters. Developers usually are never satisfied with their skills. They are always eager to become better–probably why you’re doing this. It’s really hard to justify “good developer”. People like you will become better than me in no time. I still don’t think I am a good developer.

Q: What was the most difficult thing when you were developing Sketchware?

A: Developing Sketchware wasn’t too difficult because we had a good blueprint for the item. The direction was very clear for us to follow, so developing it was a breeze. However, there was a line we had to maintain for Sketchware–this line had two conditions:

  1. Sketchware must be an easy tool for anyone to create applications.
  2. Whatever the user takes away from Sketchware can be applied in their future career

Since we wanted Sketchware to be an efficient tool that can help users learn programming concepts, I am very considerate and think a lot when it comes to adding new features in the application.

Q: As a developer, is there something you wish you knew or fixed earlier?

A: I really wish I jumped into the Start-up world earlier. When it comes to developing, you need to be passionate and really enjoy what you do. Even if you pull 3 all-nighters, ponder all day long about a new algorithm, or stress about a new bug, everything will be okay if you’re enjoying it. It really goes back to the question #1–I get my energy from the joy I have when I develop, and that joy eventually makes you a better developer. When life hits you, most developers lose the passion for developing if you think of it as work. I used to be like that. But now, I’m really not worried–since developing brings joy to me now. Even if we run out of funds or our company burns down, it’s really okay since I am making the most out of what I am doing.


Satyajit Sahoo

Satyajit is the UX Lead at Glucosio, and Front-end Engineer at Callstack.io. He is an amazing open-source contributor; he is one of the top 5 contributors in React Native

Q: What is your background as a programmer?

A: I don’t really come from a programming background. I did my graduation in Forestry. I left post-graduation after getting a job offer and never looked back.

Q: What’s your day like on day to day basis?

A: It’s pretty boring. I wake up, order some breakfast online or go out, then start office work. In evening I go out to a bar or take a long walk if there’s enough time left. At night I mostly watch TV series or hack on side-projects.

Q: Motivation behind contributing to open source projects?

A: I’ve been involved in Open Source for a long time. When I was doing my graduation I got into Linux and got introduced to the world of Open Source. I loved it how we could learn so much from other projects. It fascinated me that developers were selfless to let us see and use the there code for free (mostly). I did a lot of Open Source projects in form of themes and apps during my college days, and it always made me happy when people forked them and changed to meet their needs, and send pull requests to fix things.

As a developer, I contribute to Open Source projects most of the time because I need a feature, or it improves something on a project I love. I think it’s better if we work together to fix stuff that is important to us rather than just filing issues.

Q: How do I become a better developer?

A: I think it’s important that we are open to new things. There’s a lot to learn, and we cannot learn if we stay in our bubble. Try new things, even if you think you can’t do it, even it looks complex on the surface. I have failed to do things so many times, but eventually succeed. In the process, I understand the problem and the solution, and then it becomes really simple.


Sonny Lazuardi Hermawan

Sonny is a JavaScript Full Stack Engineer, a React & React Native player, and an Open source enthusiast. He currently works as an Engineer at Sale Stock.

Q: How do you become a better developer?

A: I think always eager to learn is the key. Try everything, make mistakes, and learn from that mistakes. I agree that code review from partners and senior engineers will make our code better. Try publishing your own open source projects, meet other great developers and learn from them.

Q: What’s your motivation behind creating open source projects?

A: I just want the people to know about our idea, and try implementing it so that others can use our project. I’m really inspired by people that work on open source projects that used by many devs such as Dan Abramov that created redux.


Sunggu Hwang

Sunggu worked at Daum Communications for 4 years. Then, he left Daum to work at Scatter Lab as the CTO. This is his 5th year at Scatter Lab.

Q: How do you become a better developer?

A: Hmm… Becoming a good developer… Every developer has his or her own personality when it comes to programming. As an analogy, think about blacksmiths! Not all blacksmiths are alike–some enjoy crafting the best sword, while some might enjoy testing out the sword more than crafting it. I am a thinker–who plans and organizes thoughts before I carry out an action. I think a good developer knows how to write concise and clean code; you should practice this habit. Even though the trend for programming is always changing, and many people use different languages, write a piece of code that anyone can understand without comments.

Q: What do you think is the next BIG thing?

A: I’ve observed the evolution of programming languages, and I think it’s becoming more abstract every generation–procedural programming, imperative programming, functional programming… I think in the future, maybe in about 20 to 30 years, we will live in the time where the computer writes the code for us, and we just put them together like legos.

Q: What should I focus on studying?

A: I think deep learning is a must. Try different tutorials and learn it with passion. Math, algorithms–anything will help you in the long run.


Timothy Ko

Timothy is a software engineer at Snapchat. He previously worked at many places such as Riot Games, Square, etc.

Q: What do you do at Snapchat?

A: I’m a software engineer on the monetization team, so I work on anything related to making money. Some example projects are Snapchat Discover, a news platform within the iOS and Android apps; Ad Manager, a control panel used by sales and ad operations to flight ads; Ads API, which allows third-party partners to integrate their own ad platforms into Snapchat. Also, I was a past intern at Snapchat so I occasionally give talks and Q&As to upcoming interns. I’m also heavily invested in hiring and conduct a lot of interviews there.

Q: What do you do on a day-to-day basis?

A: What I’ve mentioned previously. Also, even after I pass on the work to other people, sometimes I have to go back and help support it or be part of the technical discussions on future changes. When new people join the team, usually I’m the one to ramp people up on how the code base looks like the kinds of frameworks we use, how a typical engineer workflow looks like, etc.

Q: What languages/framework do you guys mostly use?

A: For server code, it’s usually Java and for UI we use React Redux. Most teams work in google app engine, which is why we use Java, but some teams switch it up a little bit due to some app engine limitations. And of course, the product teams work in objective C for iOS and Java for Android.

Q: How do you think I can become a better developer?

A: I think the best thing to do is to do as many things as possible. I did seven internships while in school so I already had two years of work experience before I graduated. Work experience is super important because coding in a hackathon, doing personal projects, and doing school assignments are totally different than working with enterprise software and apps with real users. But you have to start somewhere, so that’s where going to school, doing personal projects, and competing in hackathons comes in. And while at work, I think the best way to succeed is to ask lots of questions and learn by doing. You can read and study all you want, but you might not understand what’s going on until you actually do it. Another thing is code reviews — you can do so much knowledge transfer by having a more senior engineer tear your code apart and tell you how to make it better. Also, if you ever come up with a proposal on how to solve a problem, getting a tech lead to bombard you with hard questions forces you to make sure you have every little detail covered.

How to get hiring managers to complete scorecards: a recruiter's guide to the conversation that actually works

Getting hiring managers to complete scorecards is less a workflow problem than a negotiation problem. The recruiters who consistently pull scorecards on time have figured out how to make completion feel like the hiring manager's win — not the recruiter's chore. This guide is about the specific conversation, timing, and lightweight systems that move debrief compliance from "chased for three days" to "in the ATS before the next interview."

If you have ever sent the fourth "gentle nudge" on a Thursday afternoon, you already know the standard advice — "make it part of your process" — doesn't survive contact with a hiring manager whose sprint just slipped. What follows is a recruiter-to-recruiter playbook on how to get hiring managers to complete scorecards without becoming the person they mute in Slack.

Why hiring managers don't complete scorecards (be honest about the cause)

Scorecard non-compliance is almost never about laziness. In our experience running assessments and interview loops for hundreds of hiring teams, the pattern breaks down into four causes, roughly in this order:

  1. The scorecard asks the wrong questions. Fields like "Culture fit: 1–5" with no rubric are impossible to fill in without feeling either dishonest or exposed to a bias complaint. Hiring managers stall because the form itself is broken.
  2. The debrief window closed. By the time a hiring manager sits down on Friday, the Tuesday interview is a blur. They either fabricate a score or avoid the task.
  3. No one has explained what the scorecard is for. If the hiring manager thinks it's an HR compliance artifact, it goes to the bottom of the list. If they think it's how the panel calibrates on the next candidate, it doesn't.
  4. The recruiter is the only person following up. When escalation never happens, the deadline is fictional.

Naming the cause changes the intervention. A recruiter who chases harder solves none of these. A recruiter who fixes the rubric, shrinks the window, reframes the purpose, or builds an escalation path solves all of them.

The conversation that actually works before the interview

The single highest-leverage moment for scorecard completion is the intake conversation with the hiring manager before the first interview is scheduled — not the reminder afterward.

In that meeting, three things get agreed:

  • The rubric. What are we actually evaluating? Three to five competencies, each with a behavioral anchor. "System design at senior level" beats "technical strength." If the hiring manager can't articulate what "good" looks like, the scorecard will fail regardless of tooling.
  • The completion window. Scorecard due within 24 hours of the interview, no exceptions. This is the number to negotiate hard on. Anything longer than 24 hours correlates with lower quality and higher attrition of detail — the research on memory decay is well-established, and interview debriefs are no exception (see the classic work summarized in Kahneman and Klein, 2009, on expert judgment, foundational but still cited).
  • The escalation. "If a scorecard isn't in by end of day the following day, I'll ping you once. If it's not in 24 hours after that, I'll loop in [the hiring manager's manager or the VP of Engineering]." Say it out loud. Get the nod.

Recruiters often skip the third item because it feels aggressive. It isn't. It's the only thing that turns the deadline into a real one. The hiring manager who agrees to escalation up front rarely needs it invoked.

How to get hiring managers to complete scorecards after the interview (the 24-hour play)

Once the interview happens, the mechanics matter more than the reminders. Here is the sequence that works:

T+0 (immediately after the interview): Send a single Slack message with the scorecard link, the candidate's name, and the specific rubric competencies to score. Not a calendar invite. Not an email. A message they can act on from their phone between meetings.

T+4 hours: If not submitted, a second message. This one includes a one-line prompt: "Quick take — recommend/no recommend and one sentence on why. You can flesh out the rubric later." Lowering the bar to a directional answer often unblocks the full submission within the hour.

T+24 hours: If still not submitted, a call — not a Slack ping. Two minutes of "walk me through what you saw" and a recruiter typing the scorecard live. This is the least popular tactic among recruiters and the most effective. It costs 10 minutes. It closes the loop.

T+48 hours: Escalation, as agreed in the intake. Once. Publicly enough that the hiring manager remembers next time.

The recruiters who complain that they "can't get scorecards in" have almost always skipped step three. They pinged four times and never picked up the phone.

Redesign the scorecard so it can be completed in five minutes

If completion still lags after the conversation and timing fixes, the form itself is the problem. A scorecard that takes 20 minutes to fill in will not get filled in.

The scorecard that gets completed on time has:

  • Three to five competencies, not 12
  • A hire/no-hire recommendation at the top, not the bottom
  • Behavioral anchors under each rating so a "3" means the same thing to every interviewer
  • One free-text field for "what would change your mind"
  • No "culture fit" field without a defined rubric — it invites bias complaints and produces no signal

The trade-off is real: shorter scorecards capture less nuance, and some engineering managers will push back that a five-competency rubric can't evaluate a staff hire. Fair point. For senior roles, add one rubric-anchored deep-dive competency rather than expanding all fields. Depth in one place beats shallowness across ten.

For teams running high-volume technical hiring, structured skills-based assessments can carry more of the evaluative load upstream, so the post-interview scorecard becomes a calibration document rather than the primary signal. That shifts the hiring manager's job from "assess from scratch" to "confirm or challenge the rubric-applied score" — which is a five-minute task, not a twenty-minute one.

The systems layer: what to automate and what to leave human

Automation helps at the edges. It doesn't fix the underlying accountability problem.

What to automate: - Scorecard link delivery immediately post-interview (most ATS platforms — Greenhouse, Lever, Ashby — do this natively) - Reminder pings at T+4 and T+24 - Dashboard visibility for the hiring manager's manager showing outstanding scorecards by owner

What to keep human: - The intake conversation and the escalation agreement - The T+24 phone call - The quarterly review of which hiring managers consistently miss and why

An honest note: vendor dashboards that promise "automated scorecard compliance" tend to overstate what automation alone can do. Reminders don't create accountability; agreements do. The system exists to make the agreement visible, not to replace it.

For teams where interview volume is high enough that the debrief bottleneck is structural — 40+ interviews a week per hiring manager — the upstream fix is reducing the number of interviews that need debriefs, not automating the debriefs harder. Tools like OnScreen handle initial screening with a deterministic rubric so the hiring manager only debriefs candidates who cleared a structured filter. Fewer interviews, tighter scorecards, better calibration.

When to stop chasing and start reporting

Some hiring managers will never comply consistently. That is a data point, not a failure of the recruiter. Track scorecard completion rate by hiring manager as a quarterly metric and share it with the head of TA and the hiring manager's own leader.

The pattern usually breaks one of three ways: - The hiring manager improves once completion is visible - Their leader intervenes - The organization decides that hiring manager shouldn't be leading loops

All three are acceptable outcomes. What isn't acceptable is a recruiter absorbing the compliance cost silently, quarter after quarter, while candidates drop out because feedback took eight days.

Frequently asked questions

How long should hiring managers have to complete scorecards? 24 hours from the end of the interview. Beyond that, memory decay and calendar pressure combine to produce either fabricated scores or no scores at all. Some teams allow 48 hours for senior loops with system design components; that's the outer limit worth defending.

What's a realistic scorecard completion rate to target? Above 85% within the agreed window is achievable for teams that run the intake conversation and the T+24 phone call. Above 95% requires the escalation path to be real and occasionally invoked. Teams that report 100% compliance are usually not measuring accurately.

Should recruiters fill in scorecards on the hiring manager's behalf? Only during a live 10-minute call where the hiring manager talks and the recruiter types, with the hiring manager reviewing and submitting. Recruiters filling in scorecards asynchronously creates a defensibility problem — the person who observed the interview didn't document it — and undermines calibration.

How do you handle a hiring manager who refuses to use the rubric? Escalate once, then involve the head of TA. Rubric-free hiring is a defensibility risk under most fair-hiring frameworks and a calibration risk regardless of geography. This isn't a preference conversation; it's a program-level decision that a recruiter shouldn't be absorbing alone.

Does AI-generated candidate content change how scorecards should work? Yes. If your screening upstream doesn't verify that the candidate you interviewed is the candidate who did the take-home, the scorecard rubric should include a "consistency with prior signal" check. Interviewers flag divergence; recruiters investigate. This is one of the fastest-growing sources of late-stage no-hires we see.

Key takeaways

  • The conversation before the first interview matters more than the reminder after — negotiate the rubric, the 24-hour window, and the escalation path up front.
  • Redesign scorecards to five minutes of work: three to five competencies, behavioral anchors, and a hire/no-hire at the top.
  • The T+24 phone call is the highest-leverage recruiter move for scorecard completion and the most consistently skipped.
  • Automation supports accountability but doesn't create it — agreements do.
  • Track completion rate by hiring manager quarterly; make the data visible to their leader.

Next steps

If scorecard compliance is downstream of an interview process that's simply running too hot, the upstream fix — structured screening that reduces the number of full-loop interviews — often does more than any workflow change.

How to Run a Hiring Intake Meeting That Builds a Rubric

Meta title: How to run a hiring intake meeting that builds a rubric Meta description: How to run a hiring intake meeting that produces a usable rubric, not a wish list. A 60-minute agenda, questions, and traps to avoid.

How to run a hiring intake meeting that produces a usable rubric, not a wish list

Most technical hiring fails at the intake meeting. The recruiter walks out with a job description, a list of "must-haves" that reads like a LinkedIn profile of the departing engineer, and no shared definition of what "strong" actually looks like. Learning how to run a hiring intake meeting that produces a usable rubric — not a wish list — is the highest-leverage thing a recruiter can do for a req.

This is not a strategy exercise. A hiring intake meeting done well takes 60 to 90 minutes, produces a scoring rubric two interviewers can apply to the same candidate and reach the same score, and gets calibrated once with a real resume before the first candidate hits the pipeline. Done badly, it produces a wish list, three months of misaligned debriefs, and a closed req that took twice as long as it should have.

Why most intake meetings produce wish lists, not rubrics

The default intake meeting is a monologue. The hiring manager describes an ideal person, the recruiter takes notes, and both parties leave feeling productive. Six weeks later, when a candidate scores 4/5 on "communication" from one interviewer and 2/5 from another, nobody can point to the source of the disagreement — because the source is that "communication" was never defined.

A wish list has three tells: it lists traits instead of behaviors, it does not distinguish must-haves from nice-to-haves, and it cannot be applied to two different candidates and produce comparable scores. A rubric fixes all three. Research from Google's Project Oxygen and the widely cited Kahneman, Rosenfield, Gandhi, and Blaser work on noise in judgment shows that structured evaluation criteria — not smarter interviewers — reduce inconsistency in hiring decisions.

The wish-list-to-rubric conversion is the actual work of the intake meeting. Everything else is paperwork.

What a usable rubric looks like

A usable rubric names 5 to 8 skills, defines each with an observable behavior, assigns a weight, and specifies which interview stage evaluates it. It fits on one page. Two interviewers reading it independently and scoring the same candidate should land within one point of each other on a 5-point scale.

Here is the minimum viable structure:

  • Skill: the capability being evaluated (e.g., "system design for services at 1K+ RPS")
  • Definition: one sentence describing what "meets bar" looks like in behavior, not adjectives
  • Weight: must-have, strong-preference, or nice-to-have
  • Stage: which interview round tests this — take-home, technical screen, panel, or hiring-manager round
  • Anchor examples: one description of a 3/5 answer and one of a 5/5 answer

If any row in the rubric cannot be filled in during the intake, that skill is not ready for evaluation. Either the hiring manager needs to think harder, or the skill needs to be cut.

Skills Listed vs. Skills That Belong in a Usable Rubric
Source: Illustrative based on article claims ('typically get 12 to 20 items')

The 60–90 minute intake agenda

Block a full 90 minutes. Meetings under 45 minutes almost always produce wish lists because there is no time to force the specificity conversation. The agenda below assumes the recruiter runs the meeting and the hiring manager is the primary participant, with an optional second interviewer joining for the last 30 minutes to pressure-test the rubric.

Minutes 0–10: Confirm the role's business context

Open with the question the hiring manager has probably not been asked: what does this person deliver in their first six months that makes the hire worth it? Not their responsibilities. Their outputs.

If the answer is vague ("contribute to the team," "help us scale"), keep pressing. A senior backend hire whose first six months are "ship the payments-service rewrite" is a different rubric from one whose first six months are "stabilize on-call and reduce SEV1s." Both are legitimate, but they weight skills differently.

Minutes 10–25: List the skills, then cut half

Ask the hiring manager to list every skill they think matters. Write them all down without pushback. You will typically get 12 to 20 items — some technical, some behavioral, some cultural, some that are actually the same thing renamed.

Then do the cut. Force the hiring manager to rank the list and mark only 5 to 8 as must-haves. The rest become nice-to-haves or get removed. A rubric with 15 must-haves is a rubric that will fail candidates for the wrong reasons and will not survive contact with a real pipeline.

This is the moment where hiring managers push back. A common objection: "But I need someone who has all of these." The honest answer: candidates with all of them exist but will not accept your offer at the salary band you have approved. Pick the 5 to 8 you will actually reject on.

Minutes 25–50: Convert each skill into observable behavior

For each must-have, ask three questions:

  1. What does a candidate say or do that shows they have this? Not "they seem confident" — "they explain the trade-off between eventual consistency and strong consistency without prompting."
  2. What would a candidate say or do that shows they don't? This one is harder and more useful. Interviewers score more reliably when they have a clear negative anchor.
  3. Which interview stage tests this? If the answer is "the whole loop," the skill is not defined tightly enough.

This is the section where 30 minutes disappears fast. It is also the section that determines whether the rubric is usable.

Minutes 50–70: Assign weights and design the loop

With the skills defined, decide what fails a candidate. If a staff engineer candidate is weak on system design, is that a rejection or a discussable? If they are weak on cross-team communication, same question.

Then map each skill to a stage. A useful test: no stage should evaluate more than three skills, and no skill should be evaluated by more than two stages. If your take-home is trying to evaluate coding quality, system design, testing discipline, and communication, it is evaluating none of them well.

For teams using platforms like HackerEarth Assessments or FaceCode, this is the point to decide which skills get an automated assessment and which need a live evaluator. Automated scoring is more consistent for well-defined coding skills; live evaluation is more useful for judgment, communication, and edge-case reasoning.

Minutes 70–90: Calibrate with a real resume

Pull a resume from a candidate the team has hired in the past 12 months, ideally one everyone agrees was a good hire. Score them against the rubric you just built.

If the rubric would have rejected the person you just agreed was a good hire, the rubric is wrong. Fix it now. If two people at the meeting score the same resume more than one point apart on any skill, the definition for that skill is not tight enough. Fix it now.

Then do the same exercise with a candidate who was hired and did not work out. The rubric should have flagged them.

The three questions that separate rubrics from wish lists

When you find yourself running low on time, these are the three questions that do the most work:

"What behavior would I see?" Cuts through trait language ("smart," "driven," "collaborative") and forces observable definitions.

"Would I reject a candidate for this alone?" Sorts must-haves from nice-to-haves faster than any ranking exercise.

"Where in the loop does this get tested?" Exposes skills the team wants to evaluate but has no mechanism for.

If the hiring manager cannot answer these three for a given skill, the skill does not belong in the rubric yet.

Where intake meetings still fail — and honest trade-offs

Even a well-run intake meeting has limits. Three failure modes we see repeatedly:

Rubric drift after six weeks. The rubric is calibrated once at intake and then never revisited. By the tenth candidate, each interviewer is applying their own drift. The fix is not more training — it is a 15-minute re-calibration meeting after the first three candidates go through the full loop.

The hiring manager wasn't the hiring manager. In matrixed orgs, the person in the intake meeting is not always the person who approves the offer. If the actual decision-maker is a skip-level, get them in the room or accept that the rubric will be relitigated.

The rubric is right and the pipeline is wrong. A tight rubric applied to a weak pipeline produces the same result as a loose rubric applied to a strong one — closed reqs and unhappy hiring managers. Rubric work does not fix sourcing.

A rubric is also not a substitute for judgment on senior hires. For staff-and-above roles, the rubric constrains the debrief; it does not make the decision. That is a feature, not a bug.

Frequently asked questions

How long should a hiring intake meeting actually take?

60 to 90 minutes for a new role. 30 minutes for a backfill on an existing rubric. Meetings under 45 minutes for new roles almost always skip the specificity conversation and produce wish lists. If the hiring manager cannot give you 90 minutes, split the intake into two 45-minute meetings — one for skills, one for weights and calibration.

Who needs to be in the intake meeting besides the recruiter and hiring manager?

At minimum, one senior interviewer who will be on the loop. They pressure-test the rubric in the last 30 minutes and catch skills the hiring manager over- or under-weights. For roles where the hiring manager does not have the deepest technical expertise (common for eng managers hiring specialists), a technical peer is not optional.

How does a rubric differ from a scorecard?

A rubric defines what is being evaluated and what "meets bar" looks like. A scorecard is the form an interviewer fills out during or after the round. The rubric is the source of truth; the scorecard is the artifact. Most teams have scorecards without rubrics, which is why their scorecards do not agree with each other.

What if the hiring manager refuses to cut skills from the must-have list?

Ask them to rank the list and identify the bottom three. Then ask: "If a candidate was strong on the top five and weak on these three, would you reject them?" If the answer is no, those three are nice-to-haves. If the answer is yes, you have a compensation-band problem, not a rubric problem.

Can AI interview tools replace the intake meeting?

No. AI interview tools like HackerEarth's OnScreen apply a rubric consistently across candidates, which is valuable. They do not build the rubric. The intake meeting is where humans decide what to evaluate; the tooling decides how consistently to evaluate it.

Key takeaways

  • A usable rubric has 5–8 must-haves with observable behaviors, weights, and stage assignments — not a wish list of traits.
  • Block 60–90 minutes for a new-role intake; anything shorter skips the specificity conversation that separates rubrics from wish lists.
  • Calibrate the rubric against a real past hire before the first candidate enters the pipeline — if the rubric would have rejected a known good hire, fix it.
  • Re-calibrate after the first three candidates go through the loop; rubric drift is the most common post-intake failure.
  • Rubrics constrain debriefs but do not replace judgment on senior hires — and no rubric fixes a weak pipeline.

AI Interviews in 2026: What Candidates and Hiring Teams See

[Featured image placeholder — flag for visual asset assignment before publication]

AI interviews in 2026 are structured, avatar-led technical conversations that evaluate candidates against a fixed rubric, typically conducted asynchronously without a live interviewer present. If you run engineering hiring, these sessions have likely already changed how your funnel operates. Most of the debate about them has focused on whether they work. The more useful question, now that they're deployed at scale, is what actually happens on both sides of the screen.

The category itself has matured quickly, and platforms in this space are now moving from pilot to production across enterprise deployments. The candidate experience has changed more than most hiring teams realize, and the operational gains are real but narrower than the vendor decks suggest. This piece is the practitioner's read on what the current generation looks like from both seats.

Line chart showing AI interview deployments shifting from mostly pilot programs in 2023 to majority production use by 2026
Chart: HackerEarth internal observation across enterprise deployments, 2023–2026.

What an AI Interview in 2026 Actually Looks Like

The current generation is not a chatbot with a scorecard. A candidate joins a video session with a lifelike avatar, verifies identity through a KYC-style check, and moves through a role-calibrated conversation that adapts based on their responses. Structured technical questions and follow-ups run inside the same session, with the AI probing shallow answers and applying the same rubric to every candidate.

Session length and format

Session lengths vary by customer configuration; teams commonly configure mid-level engineering rounds in the 45–75 minute range, with longer loops for senior roles. These are estimates based on how customers set up sessions rather than platform defaults.

Proctoring without the friction

Enterprise-grade proctoring monitors for irregularities without adding the intrusive lockdown steps — forced browser lockdowns, repeated identity re-checks mid-session — that plagued earlier remote-hiring tools.

Why the format feels different

What's different from 2023-era attempts: the interviews feel like conversations. That change alone has shifted the candidate reaction more than any feature list. For teams building their own evaluation frameworks, our guide to technical assessments for engineering hiring covers how to translate role expectations into scorable signals the AI can apply consistently.

The Candidate Experience of AI Interviews in 2026

Candidates report three things consistently: relief at the scheduling flexibility, discomfort at the loss of rapport, and a specific new anxiety about "performing for the machine."

Scheduling flexibility

The scheduling win is real. A candidate who applies at 11 PM on a Sunday can complete a full technical interview before Monday standup. For candidates weighing competing offers, that speed matters — hiring teams report that funnels still routed through a human recruiter's calendar lose top-of-funnel candidates to faster-moving competitors.

Rapport loss, by seniority

The rapport loss is also real, and it's not evenly distributed. Junior candidates and career-switchers — people who benefit from a warm human read of their potential — describe these sessions as harder to "recover" from a bad start. Senior engineers, who are usually being evaluated on specific technical judgment, report the opposite: they prefer the consistency and the absence of small talk.

The new "performing for the machine" anxiety

This anxiety is worth naming. Candidates ask whether looking away from the camera counts against them, whether the AI penalizes pauses for thought, whether their accent affects scoring. Most of these fears are unfounded on well-built platforms, but the fears themselves affect performance. Hiring teams that publish a plain-English candidate FAQ — what the AI evaluates, what it doesn't, how to appeal — see fewer drop-offs.

What AI Interviews in 2026 Change for Hiring Teams

The operational math shifts in four places:

Senior engineer time recovered

The most consistent gain we see: staff and principal engineers stop losing 5+ hours a week to first-round screens. That time returns to shipping, code review, and later-stage interviews where their judgment actually matters.

Time-to-hire compresses on the front end

As Pawan Kuldip, Head of Human Resources at Discover Dollar Inc., described in a HackerEarth customer story: "Roles that previously took much longer are now being closed within three to four weeks." Front-end compression is where the gain sits — offer negotiation and reference checks still take the same time they always did.

Proxy candidates and AI-generated CVs get filtered earlier

KYC verification at interview stage catches a category of fraud that resume screening cannot. This matters more in 2026 than it did in 2023, because the tooling on the candidate side has also improved. Talent leaders across the industry — including in SHRM's 2024 Talent Trends reporting — have raised AI-generated application materials as an area of concern.

Rubric drift narrows

When every candidate answers the same core questions with the same follow-up logic, calibration meetings shorten. Panels stop arguing about whether Candidate A "seemed sharper" than Candidate B; they argue about the score deltas. HackerEarth's skills-based hiring resources cover where rubric consistency changes panel dynamics.

None of this eliminates the human interview. It reallocates where humans spend their time.

Where AI Interviews in 2026 Still Fail

Three failure modes are worth being direct about.

Context-dependent judgment

The format evaluates what a candidate says and codes during the session. It does not evaluate whether the candidate would thrive on a team that's rebuilding its data platform under deadline pressure. That's still a human read, and hiring teams that skip the human read entirely consistently report degraded signal on cultural and contextual judgment.

Novel problem formats

Well-designed sessions handle standard technical rounds and system design conversations reliably. They struggle with unusual formats — extended pair-programming, ambiguous product-engineering problems, live debugging of a real codebase. FaceCode (HackerEarth's live technical interview platform) or a live human panel is the right tool for those rounds.

Bias profile is different, not absent

AI interviews are more consistent across candidates than human-led screens on rubric application, which reduces interviewer-mood and fatigue effects. They introduce their own patterns — some research and industry observation suggests speech-recognition accuracy can vary by accent, and rubric weights encode whoever wrote them. Any vendor claiming "zero bias" is selling you a story. The honest framing is that these systems trade one bias profile for another, and the new profile is auditable in ways the old one wasn't.

How Hiring Teams Should Structure AI Interviews in 2026

Use the format for the first technical round after resume triage, then route passing candidates into a human panel for later stages. Here's the workable pattern for most engineering funnels:

  1. Triage resumes using your standard filters.
  2. Deploy the AI interview as the first technical round. Session length is customer-configured; a common estimate is roughly 60 minutes for mid-level roles and up to 90 minutes for senior roles, though these should be tuned to your rubric rather than treated as fixed.
  3. Publish the rubric to candidates before they start — what's evaluated, how it's scored, what a passing threshold looks like.
  4. Route passing candidates into a human panel for final rounds where cultural judgment and team fit matter.
  5. Provide an appeal path so candidates can flag misreads and hiring teams can catch model drift.

Do not use this format as the only evaluation. Do not use it for hires above the director level, where the judgment call is almost entirely about context and trajectory.

Teams that follow this pattern report the operational gains without the candidate-experience backlash. Teams that try to fully automate the loop report the opposite.

Frequently Asked Questions

Are these interviews fair? More consistent across candidates than human-led screens on rubric application, less capable on context-dependent judgment. The fairness question is not "AI vs. human" — it's "which failure mode is more acceptable for this role." For high-volume screening where interviewer fatigue drives inconsistency, the AI-led format is often fairer. For senior hires where context matters, human panels are.

How long does a session take? Session lengths are customer-configured. Teams commonly set mid-level engineering rounds in the 45–75 minute range and up to around 90 minutes for senior roles. Shorter and the signal is thin; longer and candidate drop-off rises sharply.

Can candidates cheat? Less easily than on take-home assignments, more easily than on live human panels. KYC verification, proctoring, and adaptive follow-up questions catch most proxy candidates and copy-paste attempts. Determined cheaters can still find gaps — no interview format is fraud-proof.

Do candidates dislike them? Reactions split by seniority and career stage. Senior engineers generally prefer them for the scheduling flexibility and consistency. Junior candidates and career-switchers report more discomfort. Publishing what the AI evaluates and offering an appeal path reduces the negative reaction significantly.

Should the format replace human interviews entirely? No. The right pattern is AI for first-round technical screening, human panels for later rounds.

What scale can a modern AI interview platform handle? Scale is where the 2026 generation separates from earlier tools. HackerEarth has observed enterprise customers using OnScreen to screen thousands of candidates in a single weekend — in one on-file case, more than 2,000 — a throughput profile that was not achievable with the 2023-era chatbot tooling. This is a documented instance rather than a guaranteed benchmark, but it changes how you plan hiring events, campus drives, and reduction-in-force backfill windows.

Key Takeaways

  • AI interviews in 2026 are structured, avatar-led sessions with adaptive follow-ups and integrated identity verification — not chatbots.
  • The biggest operational gain is senior engineer time recovered from first-round screens, not raw time-to-hire reduction.
  • Candidate reactions split by seniority: senior engineers prefer these sessions, junior candidates struggle more.
  • The bias profile shifts rather than disappears; the new profile is auditable, but "zero bias" claims are not credible.
  • The strategic implication for hiring leaders: the AI-led first round is not a labor-saving swap for a human screen — it changes where in the funnel your most expensive engineers spend judgment, and your rubric design becomes the highest-leverage lever in the whole process.
