The Ultimate Guide To Social Recruiting

Since the pandemic first hit in 2020, it has shuttered offices and industries had to adapt on the fly to continue working remotely. The tech industry needed to throw out ancient processes and discover newer avenues, especially in the field of tech recruiting. If you guessed where I’m heading with this, then you are on the right track!

Yes, I am talking about social media, its massive reach, and one form of recruiting that has shot into the limelight – Social Recruiting. Tapping into brand new spheres of talent while adopting creative recruiting strategies is the crux of social recruiting.

Although social recruiting has been around since 2008, it has become the need of the hour and a weapon to have in your corner with the pandemic rendering everything to a remote workspace. A study by Pew Research Centre found that a whopping 72% of Americans surveyed use social media heavily. This should put into perspective the large number of promising candidates you as a recruiter are not considering by failing to source candidates through social media.

Here are our 2 cents on everything you need to knowabout social recruiting and how to kill it #likeapro, true social media style!

What is social recruiting?

Social recruiting or social media recruiting is a talent acquisition strategy that refers to the use of social media platforms like LinkedIn, Facebook, Twitter, and Instagram to source and hire candidates. You can narrow down your target audience to quickly and effectively find candidates who are the right fit for your company.

Why traditional recruiting methods will no longer cut it

The global talent, mainly Gen Z do not spend time scouring newspapers for job vacancies, rather they are busy switching between Facebook, LinkedIn, and Instagram on their phone. Posting job ads on social media is easy, attracts a wider, more diverse pool of candidates, and is cheaper. “Some companies use tools to post to Instagram from PC, schedule content, and complete other tasks.”

Bidding adios to the old ways of recruitment has become necessary to stay competitive in these fast-paced, digital-forward times. It has been proven multiple times that the traditional approach towards recruiting brings no diversity to the company, stagnates growth, eliminates a large pool of passive candidates, and lowers profits in the long run.

Providing relief to time-consuming, archaic hiring practices is the new age social recruiting approach that is considerably cost-effective with a greater chance of bridging the ever-widening gap between recruiters and talented job seekers.

What do the numbers look like for social recruiting?

Still not convinced to make the switch? Here are the current statistics of the social media recruiting landscape in 2021.

✔️A Career Profiles study shows that 91% of companies rely on social media when recruiting.

✔️86% of job seekers use social media in their job search, according to CareerArc.

✔️35% of employers increased their social recruiting efforts from last year to now, according to CareerArc.

✔️A report by PostBeyond shows that 82% of companies attract passive candidates via social media.

✔️49% of professionals use Linkedin to scout for job opportunities, as stated by HackerEarth Developer Survey, 2021.

Pitfalls of social media recruiting

Now that you’re sold on the awesomeness of social recruiting, there are some DON’Ts that you need to take note of before you kickstart your social hiring journey.

  • Don’t jump headlong into social media without a cohesive plan in place. Nobody is interested in being bombarded with generic content across different social media platforms. Identify your goals, tailor your strategy according to each platform, and measure ROI periodically to see what is working.
  • Not creating quality content to best showcase your brand, company values, workplace culture, etc., and simply posting job vacancies will never attract or engage potential candidates. Bring the personal factor to your hiring strategy, nurture relationships via your content, and maintain consistency in your efforts.
  • Don’t forget to take stock of your efforts regularly. Choose key metrics like reach, engagement, and conversion to measure activity; the results should guide your way forward.

What makes for a good social media recruiting strategy?

Social recruiting takes a little work to get right, but when well executed it represents a robust advantage. Tips to kickstart your social media recruiting strategy the right way.

#1 Put together candidate personas

Speaking to the right people is of the utmost importance. It helps you narrow down who you’re looking for. Establishing candidate personas enables you to have a targeted approach on social media.

Know what kind of profiles will be a good culture-fit and balance that with the skills necessary to be successful in the role.

#2 Choose the right social media platform

The role you’re hiring for, the industry you’re in and the persona you are trying to reach out to, dictates the platform you need to use.

Some roles may require digging deep into more niche social media platforms rather than the popular ones. You may even need to use a social media management tool to keep everything organized.

#3 Track metrics to create your pipeline of candidates

Every social network has its set of metrics that need to be monitored. For example, the best time to post on Instagram may be different than on Facebook or LinkedIn. Don’t get too engrossed in the likes and follows; make sure you’re tracking suitable recruitment metrics.

Depending on your platform and social media strategy, evaluate the given metrics monthly or quaterly to see where you stand, which platforms and strategies yield the highest quality candidates and what needs to be tweaked in your approach.

#4 Optimize your social media profiles

Most recruits consider a company based on its social media presence, which is why it is important to maintain a cohesive voice across all platforms being used. Maintain consistency in messaging that potrays the true reflection of your company’s brand and mission. Adjust settings to protect social media accounts. So you wouldn’t have to deal with the Facebook security issues or report Instagram account for getting hacked.

#5 Rope in your employees to be your ambassadors

Your existing workforce is your biggest ambassador. Leverage this at every opportunity by creating some guidelines so that employees understand the goal at hand and will create content with that in mind.

You can also create readily shareable content to make it easy for everyone to re-share, repurpose, and post on their personal social media profiles.

#6 Make use of video content

There are a lot of companies competing for top tier talent right now. The last thing you want to have happen is to get lost in the mix and lose out on a rockstar new hire.

Cut through the noise by using videos to portray the day-to-day life at your company is an effective way to reach prospective candidates.

#7 Measure how well your strategy is working

Speaking in numbers may not come naturally to recruiters but this is how you convince your stakeholders that your social hiring efforts are paying off.

Review the KPIs, goals and impacts of your social media recruiting strategy. From there, you can find your strengths and weaknesses to better adjust your resources and efforts.

We have further distilled tried and tested strategies that work for social recruiting into a cheatsheet, to simplify the process for you. Go through the step-by-step breakdown on how to approach each of the 7 tips given above to better your social media recruiting strategy.

There is a bonus takeaway included in the guide as well that helps you tailor your strategy for popular social media channels like LinkedIn, Facebook, Instagram and Twitter.

Leverage social recruiting like a pro

Social media recruiting is fast becoming the most effective hiring tactic in 2021. It enables you to showcase your company culture, reach a larger talent pool, be authentic and connect with your ideal candidates. As Gen Z and millennials make up more and more of the workforce, social media dictates the hiring strategies for recruiters to leverage upon.

Are your potential candidates on social media? Then your recruiting efforts should be, too.

21 Tech Recruiting Tools To Scale Your Hiring

The conventional methods of recruiting can no longer keep up with the rapidly changing landscape of the tech world. With it becoming increasingly difficult to find skilled talent, recruiters have to think out of the box to attract and retain the best candidates out there.

How can that be done? Technology, of course. It is the one-stop solution for most of the challenges in the tech industry. There are automated tools for every step of the recruiting lifecycle, from sourcing to onboarding.

However, there is a lot of noise in this space, and it can be hard to tell what’s real from what’s simply a good marketing pitch. You may not need tech recruiting tools for all the stages of hiring. Depending on your requirements, do your research and choose wisely.

Tech recruiting technology tools for each stage of the hiring process

Tech recruiting tools required for each stage of the hiring lifecycle

Job aggregator tools for sourcing

Talent sourcing takes up a huge chunk of time for recruiters. Without the help of sourcing tools, it will be akin to searching for a needle in a haystack. Automated job aggregator tools make it easy to grow your talent pipeline. There are plenty of avenues like job portals, placement agencies, social media, and hiring challenges to source candidates from.

Job boards and job aggregators are fundamental to the recruiting ecosystem because direct applicants make up 48% of all hires. Let’s take a look at the key features of this recruiting tool for recruiters:

  • increases the visibility of your job postings across a wide range of job boards/portals
  • carry out an in-depth search of candidates using filters like skills, experience, location, etc. to spot the best ones
  • find resumes, contact information, online portfolios, etc., and gather the data under one profile for each candidate. These profiles can be quickly added to your pipeline and you can engage with them over a period of time
  • make a quick assessment of the candidate based on their portfolio and projects
  • All the data related to a candidate can be stored on one platform with easy accessibility to the entire HR team

Job aggregators to keep in mind:

  • Indeed is said to be the largest platform for external hires with 75% of job applications coming in and 47% of all hires in the US
  • Glassdoor has its own job board where 83% of its 64 million monthly users are currently looking for a job
  • LinkedIn provides a Job Search Tool with advanced search capabilities and can filter out results based on location, skills, industry, and recommendations

Standalone applicant tracking systems (ATS)

Using numerous job boards and portals for posting your job vacancies can quickly become exhausting if you have to do it manually. A study by GetApp shows that 86% of recruiters say using an ATS has increased the speed at which they hire candidates.

A good ATS, recruitment technology tool offers capabilities like:

  • job opening posting across multiple job boards and websites
  • automated screening of candidates, and their resumes, which also decreases human bias and errors
  • database assistance where you can store all applicants’ information
  • view the status of each candidate throughout the interview process
  • send out assessment invites from the ATS itself to the selected candidates and prepare a performance report in real-time
  • initiate offer letters directly from the ATS, get them signed by the candidates and save the documents digitally on the cloud

Offering most of the features listed above, we have some good ATS options in the mix like:

  • Lever, a San Francisco startup, focuses on diversity and metric-based recruiting
  • Naukri RMS, automates the hiring process from end-to-end
  • LinkedIn Talent Hub, allows customers to source, manage, and hire in one integrated platform

Recruitment CRM tools for engagement

Waiting for a role to open to begin scouting for skilled developers is not a good idea. Instead, build and maintain a talent pool of passive candidates. Keep them engaged with company updates and relevant content so that you know exactly whom to approach for any role when the time comes. This is where recruitment CRM tools step in. They help in:

  • building a personal connection with the candidates during the hiring process
  • keep your candidates in the know by sending timely updates at each stage of the process
  • reduce time-to-hire by eliminating manual data entry and increase productivity with collaborative hiring
  • effectively engage prospective candidates through social media
  • nurture and engage candidates who were not hired in this phase but can be given an opportunity in the future

Recruitment CRM tools that need to be tried out for yourself:

  • Zoho has a cloud-based CRM platform that offers diverse solutions for building a relationship with your candidates
  • Yello provides an automated talent acquisition platform with a variety of services
  • Beamery, a London-based startup offers self-styled recruitment marketing software

Tech screening and assessment software

With scores of applications coming in, it is a huge task for recruiters to identify the ones worth talking to. Do the applicants with great resumes possess the skills that they say they have? The technical screening round is designed to filter candidates who exhibit the skills they listed on their resumes. Additionally, assessments are an effective way to test the behavioral and technical skills of developers. Coding assessment tools provide features like:

  • create highly accurate coding assessments or even custom ones based on the job role/skills/experience with minimum technical knowledge
  • make use of an extensive inbuilt library of questions across programming languages and skills with a robust proctoring system
  • set standard benchmarks for performance to shortlist candidates easily
  • sync seamlessly with your existing ATS to keep candidate information in one place

Screening tools that make the lives of recruiters easy:

  • HackerEarth Assessments helps you to objectively evaluate developers with a rich library of 13K+ questions across 80+ skills and shortlist candidates based purely on their performance
  • DevSkiller provides an automated technical screening platform that assesses candidates based on their skills
  • CodeSignal offers coding tests and assessments for hiring at scale

Coding interview tools

HackerEarth’s recent developer survey showed that 40% of developers preferred to be interviewed on interview tools that are equipped with code editors and video conferencing. For a fair and objective screening and evaluation of the applicants, coding interview tools are the best choice. They offer features such as:

  • conduct structured interviews with standard evaluation parameters
  • have real-time code editors with built-in compilers (doing away with whiteboards)
  • allow pair-programming
  • have AI-powered functionalities
  • provide real-time feedback and automated summary of each interview
  • enable blind interviewing to combat bias in the process

Coding interview tools that come with most of the functionalities given above:

  • FaceCode allows you to invite and conduct coding interviews on a collaborative, real-time code editor that also automates your interview summaries
  • CoderPad offers an intuitive programming interface that enables you to leave the whiteboard behind
  • CodeBunk provides an online real-time editor and compiler for interviewing developers

Background check tech recruiting tools

You are ready to roll out the offer letter as the selected candidate has excelled in all the rounds of interviews. It is advisable to conduct a background check before that to avoid making a bad hire as well as for additional security purposes. Some advanced features of such tools include:

  • an applicant’s ID verification, credit check, drug screening, and social media check
  • an applicant’s civil court records, motor vehicle records, and fingerprints for a more detailed verification
  • recruiters can create custom screening packages according to job role or department

This helps create a fuller picture of the candidate to deem whether they will be a good fit for the company. Some useful tools to try out include:

  • GoodHire provides an easy employee background check experience with its pre-bundled and custom-designed packages
  • Sterling helps create safer environments for your employees with its myriad background check services
  • Verified First enables accelerated background screening of candidates with its platform

Onboarding and core HR management software

Onboarding tools

Recruitment doesn’t end once the candidate signs the offer letter. There’s still the matter of onboarding. You are given one shot to make a great first impression on your new joiner and you do not want them to be blinded by paperwork.

With nearly 58% of organizations focusing their onboarding programs on lengthy processes and paperwork, only 12% of employees feel that their organization does a great job of onboarding. This is a wake-up call for organizations to switch to suitable tools for onboarding.

Now, let’s help make onboarding enjoyable for you and the candidate with the latest tech recruiting tools in the market. They have automated capabilities to:

  • help new hires self-onboard themselves with a checklist of tasks
  • finish filling out paperwork like offer letters, tax forms, and company NDAs ahead of time
  • customize the onboarding workflows like creating email addresses, allocating company devices, etc. for different candidates
  • introduce them to the rest of the team with welcome emails

HR management tools

Now that you have onboarded your new joiners, the next step is to ensure they have an easy and hassle-free employee experience. An integrated HR management tool allows you to manage the entire employee lifecycle from a single platform.

  • has self-service options for availing leaves, travel reimbursements, and timesheet entry
  • takes care of performance management and employee engagement
  • provides payroll and tax filing services
  • encourages internal collaboration among employees

(Part 2) Essential Questions To Ask When Interviewing Developers In 2021

The first part of this blog stresses the importance of asking the right technical interview questions to assess a candidate’s coding skills. But that alone is not enough. If you want to hire the crème de la crème of the developer talent out there, you have to look for a well-rounded candidate.

Honest communication, empathy, and passion for their work are equally important as a candidate’s technical knowledge. Soft skills are like the cherry on top. They set the best of the candidates apart from the rest.

Re-examine how you are vetting your candidates. Identify the gaps in your interviews. Once you start addressing these gaps, you find developers who have the potential to be great. And those are exactly the kind of people that you want to work with!

Let’s get to it, shall we?

Hire great developers

What constitutes a good interview question?

An ideal interview should reveal a candidate’s personality along with their technical knowledge. To formulate a comprehensive list of questions, keep in mind three important characteristics.

  • Questions are open-ended – questions like, “What are some of the programming languages you’re comfortable with,” instead of “Do you know this particular programming language” makes the candidate feel like they’re in control. It is also a chance to let them reply to your question in their own words.
  • They address the behavioral aspects of a candidate – ensure you have a few questions on your list that allow a candidate to describe a situation. A situation where a client was unhappy or a time when the developer learned a new technology. Such questions help you assess if the candidate is a good fit for the team.
  • There is no right or wrong answer – it is important to have a structured interview process in place. But this does not mean you have a list of standard answers in mind that you’re looking for. How candidates approach your questions shows you whether they have the makings of a successful candidate. Focus on that rather than on the actual answer itself.

Designing a conversation around these buckets of interview questions brings you to my next question, “What should you look for in each candidate to spot the best ones?”

Hire GREAT developers by asking the right questions

Before we dive deep into the interview questions, we have to think about a few things that have changed. COVID-19 has rendered working from home the new normal for the foreseeable future. As a recruiter, the onus falls upon you to understand whether the developer is comfortable working remotely and has the relevant resources to achieve maximum productivity.

#1 How do you plan your day?

Remote work gives employees the option to be flexible. You don’t have to clock in 9 hours a day as long as you get everything done on time. A developer who hasn’t always been working remotely, but has a routine in place, understands the pitfalls of working from home. It is easy to get distracted and having a schedule to fall back on ensures good productivity.

#2 Do you have experience using tools for collaboration and remote work?

Working from home reduces human interaction heavily. There is no way to just go up to your teammate’s desk and clarify issues. Virtual communication is key to getting work done. Look for what kind of remote working tools your candidate is familiar with and if they know what collaborative tools to use for different tasks.

Value-based interview questions to ask

We went around and spoke to our engineering team, and the recruiting team to see what questions they abide by; what they think makes any candidate tick.

The result? – a motley group of questions that aim to reveal the candidate’s soft skills, in addition to typical technical interview questions and test tasks.

#3 Please describe three recent projects that you worked on. What were the most interesting and challenging parts?

This is an all-encompassing question in that it lets the candidate explain at length about their work ethic—thought process, handling QA, working with a team, and managing user feedback. This also lets you dig enough to assess whether the candidate is taking credit for someone else's work or not.

#4 You’ve worked long and hard to deliver a complex feature for a client and they say it’s not what they asked for. How would you take it?

A good developer will take it in their stride, work closely with the client to find the point of disconnect, and sort out the issue. There are so many things that could go wrong or not be to the client’s liking, and it falls on the developer to remain calm and create solutions.

#5 What new programming languages or technologies have you learned recently?

While being certified in many programming languages doesn't guarantee a great developer, it still is an important technical interview question to ask. It helps highlight a thirst for knowledge and shows that the developer is eager to learn new things.

#6 What does the perfect release look like? Who is involved and what is your role?

Have the developer take you through each phase of a recent software development lifecycle. Ask them to explain their specific role in each phase in this release. This will give you an excellent perspective into a developer’s mind. Do they talk about the before and after of the release? A skilled developer would. The chances of something going wrong in a release are very high. How would the developer react? Will they be able to handle the pressure?

#7 Tell me about a time when you had to convince your lead to try a different approach?

As an example of a behavioral interview question, this is a good one. The way a developer approaches this question speaks volumes about how confident they are expressing their views, and how succinct they are in articulating those views.

#8 What have you done with all the extra hours during the pandemic?

Did you binge-watch your way through the pandemic? I’m sure every one of us has done this. Indulge in a lighthearted conversation with your candidate. This lets them talk about something they are comfortable with. Maybe they learned a new skill or took up a hobby. Get to know a candidate’s interests and little pleasures for a more rounded evaluation.

Over to you! Now that you know what aspects of a candidate to focus on, you are well-equipped to bring out the best in each candidate in their interviews. A mix of strong technical skills and interpersonal qualities is how you spot good developers for your team.

(Part 1) Essential Questions To Ask When Recruiting Developers In 2021

The minute a developer position opens up, recruiters feel a familiar twinge of fear run down their spines. They recall their previous interview experiences, and how there seems to be a blog post a month that goes viral about bad developer interviews.

While hiring managers, especially the picky ones, would attribute this to a shortage of talented developers, what if the time has come to rethink your interview process? What if recruiters and hiring managers put too much stock into bringing out the technical aspects of each candidate and don’t put enough emphasis on their soft skills?

A report by Robert Half shows that 86% of technology leaders say it’s challenging to find IT talent. Interviewing developers should be a rewarding experience, not a challenging one. If you don’t get caught up in asking specific questions and instead design a simple conversation to gauge a candidate’s way of thinking, it throws up a lot of good insight and makes it fun too.

Developer Hiring Statistics

Asking the right technical interview questions when recruiting developers is important but so is clear communication, good work ethic, and alignment with your organization’s goals.

Let us first see what kind of technical interview questions are well-suited to revealing the coding skills and knowledge of any developer, and then tackle the behavioral aspects of the candidate that sets them apart from the rest.

Recruit GREAT developers by asking the right questions

Here are some technical interview questions that you should ask potential software engineers when interviewing.

#1 Write an algorithm for the following

  1. Minimum Stack - Design a stack that provides 4 functions - push(item), pop, peek, and minimum, all in constant order time complexity. Then move on to coding the actual solution.
  2. Kth Largest Element in an array - This is a standard problem with multiple solutions of best time complexity orders where N log(K) is a common one and O(N) + K log(N) is a lesser-known order. Both solutions are acceptable, not directly comparable to each other, and better than N log(N), which is sorting an array and fetching the Kth element.
  3. Top View of a Binary Tree - Given a root node of the binary tree, return the set of all elements that will get wet if it rains on the tree. Nodes having any nodes directly above them will not get wet.
  4. Internal implementation of a hashtable like a map/dictionary - A candidate needs to specify how key-value pairs are stored, hashing is used and collisions are handled. A good developer not only knows how to use this concept but also how it works. If the developer also knows how the data structure scales when the number of records increases in the hashtable, that is a bonus.

Algorithms demonstrate a candidate’s ability to break down a complex problem into steps. Reasoning and pattern recognition capabilities are some more factors to look for when assessing a candidate. A good candidate can code his thought process of the algorithm finalized during the discussion.

#2 Formulate solutions for the below low-level design (LLD) questions

  • What is LLD? In your own words, specify the different aspects covered in LLD.
  • Design a movie ticket booking application like BookMyShow. Ensure that your database schema is tailored for a theatre with multiple screens and takes care of booking, seat availability, seat arrangement, and seat locking. Your solution does not have to extend to the payment option.
  • Design a basic social media application. Design database schema and APIs for a platform like Twitter with features for following a user, tweeting a post, seeing your tweet, and seeing a user's tweet.

Such questions do not have a right or wrong answer. They primarily serve to reveal a developer’s thought process and the way they approach a problem.

#3 Some high-level design (HLD) questions

  • What do you understand by HLD? Can you specify the difference between LLD and HLD?
  • Design a social media application. In addition to designing a platform like Twitter with features for following a user, tweeting a post, seeing your tweet, and seeing a user's tweet, design a timeline. After designing a timeline where you can see your followers’ tweets, scale it for a larger audience. If you still have time, try to scale it for a celebrity use case.
  • Design for a train ticket booking application like IRCTC. Incorporate auth, features to choose start and end stations, view available trains and available seats between two stations, save reservation of seats from start to end stations, and lock them till payment confirmation.
  • How will you design a basic relational database? The database should support tables, columns, basic field types like integer and text, foreign keys, and indexes. The way a developer approaches this question is important. A good developer designs a solution around storage and memory management.
Here’s a pro-tip for you. LLD questions can be answered by both beginners and experienced developers. Mostly, senior developers can be expected to answer HLD questions. Choose your interview questions set wisely, and ask questions relevant to your candidate’s experience.

#4 Have you ever worked with SQL? Write queries for a specific use case that requires multiple joins.

Example: Create a table with separate columns for student name, subject, and marks scored. Return student names and ranks of each student. The rank of a student depends on the total of marks in all subjects.

Not all developers would have experience working with SQL but some knowledge about how data is stored/structured is useful. Developers should be familiar with simple concepts like joins, retrieval queries, and the basics of DBMS.

#5 What do you think is wrong with this code?

Instead of asking developer candidates to write code on a piece of paper (which is outdated, anyway), ask them to debug existing code. This is another way to assess their technical skills. Place surreptitious errors in the code and evaluate their attention to detail.

Now that you know exactly what technical skills to look for and when questions to ask when interviewing developers, the time has come to assess the soft skills of these candidates. Part 2 of this blog throws light on the how and why of evaluating candidates based on their communication skills, work ethic, and alignment with the company’s goals.
