A hiring manager’s guide to hiring the right developer

We all know that hiring the right developeris a lot of hard work; you have to identify your requirements, find the right candidate, then integrate them into your team smoothly. Studies reveal that almost 24% percent of employers admit that they face considerable difficulties when searching for tech candidates. What’s worse, over 50% of businesses hire tech employees who don’t meet their top job requirements.

While this process isn’t a simple one, there is nothing like the energy that a talented and motivated employee can bring to your organization. The result is not only a tech project finished on time but an exciting new addition to your company that will make a lasting impact.

Read on to find out how intuitive tech managers attract and hire stellar developers.

1. Identify your requirements

Figure out the type of problems you are trying to solve, the challenges your candidate will face, and the outcomes you want to achieve. From there, let the nature of the work and the goals of the position determine the strengths, innate traits, and foundational knowledge that a candidate needs to possess. For example, if you are looking to hire the right software developer, the key skills to look for are mathematical aptitude, problem-solving, knowledge of programming languages such as Java and Python, accuracy and attention to detail, etc. While you may be an expert, it is always wise to bring more technical expertise and resources into recruiting. You can put your developer team in a room together and talk to them about how you can hire people like them. They can help you with the correct terminologies that are must-have and nice-to-have.

2. Get everyone on the same page

It is of utmost importance for the hiring manager, the development team, and the leadership team to be on the same page about who they are looking to hire, what will be the employee’s responsibilities, what primary technical skills are required, and how the person’s success in the role will be gauged. By having a clear understanding of expectations early on in the process, hiring managers can make sure candidates can perform the tasks efficiently which will be required as part of the role.

3.Know where to find developers

The goal in the sourcing stage is to attract as many talented developers as possible. Piquing interest is key and a simple and gender-fluid job description will definitely help you.

There are different resources that you can use to while hiring the right developers:

  1. Developer communities: Tech communities are full of potential hires waiting to be discovered. Communities from where you can source talent for free include GitHub, Stack Overflow, and Hacker News.
  2. Personal networking: Sometimes, things that we are looking for are right in front of us and we hardly notice them. Take for example your company’s Linkedin profile. You can find some great candidates just by looking at it closely. Also, make use of your personal and professional contacts and resources. Attend local meetups in your area for entrepreneurs in technology and you will find that there are many people who might just be looking for this kind of position.
  3. Social media: Did you know that 53% of young online adults aged 18–29 use Instagram actively? Social media is a powerhouse of talent if used the right way.
  4. Virtual job fairs: This is not exactly a cost-free way of sourcing talent but it is comparatively cheaper (average of $8,000 for one virtual event) than the conventional way of recruitment.
  5. Job boards: Authentic Jobs, Mashable Job Board, Smashing Magazine Jobs, and StackOverflow Careers 2.0 are our top picks.

4. Start with a conversation and only then jump to take-home coding tests

Pre-employment or take-home coding tests are an absolute necessity for evaluating the skills of a developer. However, tossing them at a busy developer in the early stages will drive them away. Hence, before you give them a test of any sort, start with a face-to-face or telephonic discussion about prior work experience and technical projects that they have worked on. This allows both the employer and employee to assess the chemistry and fit, learn from each other, and decide if moving forward with a coding test or additional interviews makes sense.

5. Listen, learn, and collaborate during the interview

Each employer should be asking open-ended, thought-provoking questions to begin a dialogue with the interviewee. Some examples include:

  • Tell me something about a project that you are working on: By asking this question, you should be able to get the developer talking in a comfort area. If candidates are strategic in their answers, they will pick an area that’s aligned to the role they are interviewing for. Look for a candidate’s ability to tell a story and whether they can explain why they are working on it. This question acts like an ice-breaker that can lead to several other questions and discussion areas that will help you understand who is sitting in front of you.
  • Where are you in your job search?: In addition to being a good ice-breaker, asking this question will also give you an idea of how far the candidate is in the job exploration and research process. Ultimately, you’re looking to understand what motivates them in the workplace, so you can assess if there is a likely fit between your technology work and their work style and aspirations.

You can also discuss the work style and practices of the potential candidate. If your candidate is someone who works remotely, you should ask questions about how they’ve been successfully working in a remote environment and the challenges they faced while collaborating with centralized teams. It is important to remember that while some developers like to mentor, others need mentoring and some prefer working alone. These questions are designed to help you evaluate whether the candidate is the right fit, whether he/she will be able to enhance the working style of the team they may join, and what may be the areas of change.

6. Hire the most promising candidate

Yay! You have finally found a great developer you’d like to hire. However, before you roll the offer letter, go with a trial first. You could give them a small project that’s complicated enough to test their problem-solving and role-specific skills and simple enough to be finished in a short time without a considerable cost. Hire the developer only if the code is right, is delivered on time, and you are satisfied with the communication and way of working. Last but not least, define expectations straight from the beginning.

There you have it; our 6-step guide to hiring the right developer. Any tips you’d like to share from your personal experience in hiring a dev? We would love to entertain a conversation. Drop a short excerpt from your experience in the comments below.

How to target passive candidates and build talent pools proactively

Talent management deserves as much focus as financial capital management in corporations

- Jack Welch, Chairman & CEO, General Electric



In these modern times, when it is extremely difficult to find and retain talent, it is smarter for companies to build a pool of top potential passive candidates. Companies can no more have a response-based approach where they start looking only after the need arises. With an existing pool of candidates, they can now hire the perfect one with much greater efficiency.

Let’s break it down for you.

What is a talent pool?

Essentially, a talent pool is a database of talented and highly qualified individuals who, at some point, have shown an interest in working for your company. Maybe there is no opening currently or maybe they weren't ideal for the role they applied to, but that doesn't mean you forget about them.

Creating a database of such individuals would help you recruit efficiently when the need arises. All you need to do is keep them engaged and interested in your company.

Who are passive candidates?

Passive candidates are those who are currently employed and are not actively looking for a new job. But their extensive experience, high qualifications, and in-demand skills make them perfect for a role in your company.

They are generally happy working at their current company in the current role, but if a new and interesting opportunity would come up, they wouldn't mind exploring it.

Why build a talent pool of passive candidates?

After understanding who passive candidates are and what talent pools are, it is important to understand why building talent pools of passive talent is one of the best strategies for any company. There are 4 main reasons for this.
  1. Less Demanding/Low Engagement

    Passive candidates are already employed and are not actively looking for a new job. Due to an already existing job, they are busy in their personal and professional lives and thus would not like to be disturbed by the constant bombardment of emails and messages or what has now become the new definition of engagement. They only want to be contacted with information that is relevant for them or an offer that makes sense.

    This makes the job easier for companies as well as they don't have to worry about constantly engaging the talent pool and creating content specifically for the pool. A monthly or quarterly newsletter is more than enough to stay in contact.
  2. Higher skills & experience

    It is known that passive candidates are already employed and are not actively looking for a new job. Then why are companies looking for them specifically and not those who are actively searching for a job instead? Well, just like Bryan Mills from Taken, they have a very specific set of skills that makes them highly sought-after, and essentially that's the reason why they currently have a satisfying job as well.

    Hence, it is imperative for companies and recruiters to be aware of the value these skills carry in the market and alter communication pieces accordingly
  3. Nurturing candidates

    With the high experience that these candidates carry, they don't just look at the salary packages or the role, but also the kind of company and the people that they would be working with to understand if it would be a good fit for them.

    Engaging with the candidates for some time and giving them insights about the kind of company it is, would keep them interested in working there. So when the time comes, they don't have to spend time to know more about the company.
  4. Most of the market is made of passive talent

    According to a report by LinkedIn, "70% of the global workforce is made up of passive talent who aren't actively job-searching". In such a market scenario where most of the talent is passive, it is crucial, it makes no sense to hunt for the perfect candidate from the small pool of only 30% of the candidates.

How to target passive candidates?

  • Leverage social media: LinkedIn has always been the most useful recruiting tool,. However, 52% of hiring managers say that passive candidate recruiting has become less effective on LinkedIn because of oversaturation. Hence, in addition to LinkedIn, you could try using Twitter. You can leverage Twitter’s advanced search functionality, use industry-related keywords and hashtags, and refine your search based on location and other important criteria to look for passive candidates. Employers can also use targeted search capabilities on Facebook to find talented passive candidates. You can incorporate other social platforms such as Instagram and Snapchat to attract passive candidates. For instance, you can create a sponsored Snapchat or Instagram advertisement as a post or story, showcasing your company culture and catching the attention of passive candidates.
  • Strengthen your brand: One great way to latch onto amazing passive candidates is by building a solid employer brand and describe the organization's reputation as an employer. Passive candidates are often attracted to organizations with employment brands that align with their goals and values. Examples of strong employment brands include employers that are known for their support of diversity and inclusion, a fun, free-thinking workplace dedicated to innovation and collaborative contributions; dedication to professional development and growth, investment in long-term employment, and leadership opportunities, and more. Once your brand is established, the next thing to do is strengthen it so word gets out to passive candidates that your organization is a good place to work.
  • Welcome employee referrals: Employee referrals are an efficient way to target passive candidates. Your team is first-hand proof of what you stand for as an employer brand. Hence, it is very important that they are your strongest advocates. Every employee in your organization has their networks and connections that often contain a significant number of candidates who might be a good fit for open positions within your company. Also, when recruiters reach out to passive job seekers, they may be hesitant to respond. However, they’re much more likely to consider an opportunity brought to them by a personal connection.
  • Invest in tools: Artificial Intelligence has changed every aspect of our life, and recruitment is not an exception. With automation tools, recruiters can locate passive candidates much quicker and more efficiently. AI can collect a wide variety of data from the web, including resume details and social media activities of candidates. Based on this data, these tools can predict whether a passive candidate is open to switching jobs. This way, recruiters can prioritize those candidates.
  • Write engaging blogs: Many organizations are increasingly using blogs as a means to connect with potential clients, bring leads, and target passive candidates. You can begin by writing blog articles on topics that people in your industry would be interested in. With the increasing number of people who consume content on a daily basis and want to remain updated on the latest trends, several companies are using blogs to target potential passive candidates.

Conclusion

In these modern times where companies are hunting for the perfect employees, it is critical for a recruiter to stay one step ahead of the game; and targeting passive candidates seems to be the perfect way to do that. With low engagement requirements and most sought after skills, these candidates are ideal for any company. Creating a pool of such candidates can help a company keep them in the loop, nurture them constantly, and hire them with much higher efficiency and ease as soon as an opening arises.

Hiring trends in a post COVID-19 world

The COVID-19 pandemic has disrupted the daily lives of people around the world. In the midst of the pandemic, the world is facing uncertainty across industries, and the recruitment industry is no different. Experts believe that the pandemic will have long-lasting effects on the recruitment industry even after it is left behind us. It will change how organizations attract, hire, and retain talent. Hence, recruiters and hiring managers have to prepare themselves to brace the changes brought about by the COVID-19 outbreak and continue to hire talented candidates. Here’s our take on a few hiring trends that the world will see in a post-COVID-19 world:

1. Recruitment strategies will shift to virtual platforms

Following the unforeseen disruption caused by the coronavirus pandemic, virtual interactions and remote interviews are replacing in-person job interviews and employee onboarding. Organizations are now resorting to intelligent automated systems that offer a virtual interviewing environment as well as provide a great onboarding experience.

Virtual platforms help the recruitment team to stay connected with candidates throughout the entire interview process without meeting them in person. Additionally, experts believe that the usage of coding assessment and video interview tools is expected to increase as part of the hiring process, especially in the tech industry.

One may ask, “Are remote hiring and onboarding just temporary solutions to tackle the COVID-19 pandemic?” We think not! Here’s why:

  • According to recent studies, recruiters reported a 67% spike in video interviews. Candidates were keen too—with a 150% increase in the number of candidates wanting to digitize their CV with a video.
  • Google has informed its candidates that interviews are to be conducted via Google Hangouts or using the organization’s videoconferencing service—BlueJeans. Also, the organization has witnessed a 60% increase in the use of Hangouts Meet.
  • Amazon has set up virtual interview portals for candidates to quickly connect with recruiters and complete necessary documents. The company has canceled several in-person interviews and leverages its video conferencing software, Amazon Chime, to conduct remote interviews with candidates.
  • According to a recent Gartner report, about 74% of CFOs expect some of their employees to continue working remotely even after the COVID-19 pandemic ends. Several organizations are planning to make flexible and remote work models a more permanent part of their cost- and workforce-management strategies after COVID-19 recedes.

Several organizations have moved to the virtual screening and onboarding process, with the aim to mitigate COVID-19-led disruption and sustain business continuity. But even beyond using virtual platforms for interviews, companies that learn to incorporate such platforms in new ways can open up a world of possibilities for reaching and communicating with candidates. That’s why virtual platforms will be one of the most relevant online recruiting strategies in the days to come.

2. Candidate applications will surge significantly

Nearly 25 million people (and counting) worldwide face unemployment as COVID paralyzes all sectors of the modern economy. A quick recovery is unlikely, says Sangheon LEE, director of employment policy at the International Labor Organization.

In such times, companies are bound to see a spike in the number of applications for a job role. According to studies, youngsters are most likely to lose their jobs or see their income drop because of the pandemic. This can have serious long-term repercussions. If this cohort’s career is disrupted or postponed by even a year, it will have to compete with the new cohorts, joining the labor force after them—arguably, for fewer jobs.

Furthermore, as work from home becomes relatively commonplace, and remote jobs have no specific location requirements, organizations will receive job applications from around the world. Hence, the candidate pool is bound to increase.

As a benchmark, the average job advert receives 59 applicants. However, companies post COVID-19 can expect to receive over 250 applicants per job position.

As a result, recruiters and hiring managers should have smart recruitment strategies in place to tackle such high volume recruiting positions.

3. University recruitment will move online

One of the most fundamental areas that is rapidly changing is university recruitment. Some of these changes were evident even before the pandemic, such as digital portfolios, social media advertisements, and phone calls. They replaced the traditional methods to ease the tedious university recruitment process. In a post-COVID-19 world, students will experience university recruitment in a different light. Where recruiters have traditionally attracted students through on-campus events and tours, they must now shift focus to online activities. A study found that almost 73% of leaders are increasing their marketing efforts during this time. The study states that leaders are reallocating

  • 18% for more content marketing
  • 15% on organic growth
  • 28% toward more online advertising
  • and 12% on social media marketing

More organizations will use Instagram and Facebook to engage with prospective students, share alumni stories, and provide valuable tips. As physical contact will become more restricted, email marketing will offer a great opportunity for recruiters to contact prospective students.

4. Number of middle-management positions will drop

The 2008 recession saw organizations pulling out all types of middle-management positions. The same trend may continue in 2021, says John Sculley, who served as Apple’s CEO from 1983 to 1993. “A lot of organizations are going to say, ‘Wait a minute, we don’t really need all these layers of middle management that we had in the past,’” Sculley tells CNBC Make It.

Roles in tech companies that were typically assigned to employees in the middle-level bracket may be handled by tools. For instance, Capgemini is using IBM’s cognitive consulting tool Watson to assign people to projects. However, one fear of flattening the middle-management structure is that fewer managers will be available to oversee a higher volume of direct reports. This will create room for error, lack of oversight, and mismanagement.

5. New employee rights will emerge

State and local governments have mandated paid sick leaves for all employees during the COVID-19 outbreak. Hence, many organizations are shifting their focus to hourly workers that were formerly excluded from such perks. It is expected that these laws and policies will accelerate even after the pandemic subsides. As organizations hire new employees and increase retention rates in the face of completion once the economy reviews, this change may become permanent. Companies will need to leverage everything available to keep their employees, partners, and customers as safe as possible.

How has tech recruitment changed after pandemic?

The recruitment landscape, and tech recruitment in specific, has been profoundly reshaped in the post-pandemic era, marked by a significant shift towards remote and hybrid work models, accelerating the digital transformation within hiring processes. Organizations now prioritize digital collaboration skills and autonomy in their search for talent, leveraging advanced digital tools and platforms for virtual interviews, digital onboarding, and AI-driven candidate screening. This transformation extends to an increased focus on employee well-being, work-life balance, and the need for flexibility, fundamentally altering not only how companies recruit but also how candidates evaluate potential employers. As a result, recruitment strategies now emphasize adaptability, digital proficiency, and a strong alignment between organizational values and candidate expectations, setting a new standard for the future of work.

Summing up…

While governments, businesses, and citizens are finding ways to overcome this catastrophe, experts are trying to analyze the impact of COVID-19 on the future of the recruitment industry. Upswings and downturns in the industry are unfortunate, but with this pandemic, one of the biggest changes in hiring trends is likely to be how the recruitment process itself is conducted. Hence, recruiters and hiring managers need to think ahead to stay on top of the curve.

Evaluation parameters that support a bias-free interview process - FaceCode

Conducting structured interviews and having pre-defined evaluation parameters are excellent ways to interview candidates in an unbiased and standardized manner. Asking a set of questions in a structured interview format helps the hiring team to collect useful information from each interviewee that they can use for making informed hiring decisions and as well as compare with other candidates in the funnel.

What are structured interviews?

A structured interview has two main components:
  • A systematic approach where you ask the same predetermined questions to all candidates
  • A standardized scoring system or evaluation parameters that help you rate all candidates
This method is more successful than the traditional interview system because the predetermined scoring systems or evaluation parameters in structured interviews help you base your interpretation of the candidate’s answer on facts and not intuition. This process also minimizes the likelihood of a bad hire and ensures that you can reduce discrimination issues or a biased hiring decision since all candidates are given the same opportunities to showcase their abilities and treated fairly.

Using FaceCode for structured interviews

To conduct standardized interviews, it’s important that you have the option to provide feedback based on a predetermined scoring mechanism. We have recently introduced a feature in FaceCode that allows you to define evaluation parameters that will enable you to conduct structured interviews. The evaluation parameters act as a private interview scorecard for interviewers to manually assess candidate skills during the interview.

How to add evaluation parameters?

Step 1: Log in to your HackerEarth Assessment account by using your admin credentials. Navigate to the panel on the left-hand side and select FaceCode.

FaceCode

Step 2: Schedule an interview on FaceCode.

Schedule an interview

Step 3: After setting up an interview, you will have the option of manually entering evaluation parameters, such as technical abilities, communication skills, problem-solving skills, and more, based on the role that the candidate is getting hired for.

Set up the interview

When the interview is over, a pop-up with these criteria is shown to the interviewers, and candidates are evaluated based on a five-star rating system against each criterion. The hiring team can compile the rating for every candidate, compare rankings, and identify the strongest ones.

And that’s it! FaceCode will ensure that your recruitment process is bias-free. Try FaceCode to refine your remote hiring process.

A collaborative online diagram board to help you seamlessly conduct system design interviews

System design interviews are an integral part of tech hiring and are conducted later in the interview process. System design interviews help you assess a candidate’s ability to design complex systems and understand their thought process for creating real-world products. While coding interviews tend to be a pass/fail system, design interviews are graded on a spectrum as they're more open-ended.

What are system design interviews?

Systems design is the process of defining, developing, and designing systems that satisfy the specific needs and requirements of a business or organization. It involves designing elements of a system, such as architecture, modules, components (and their interfaces), and data.

Some examples of system design interviews include:
  • Flowcharts: A step-wise and schematic representation of an algorithm.
  • Unified Modelling Language (UML): Helps system and software developers specify, visualize, construct, and document software systems as well as used for business modeling and other non-software systems.
  • Business Process Modelling Notation (BPMN): Used for creating a flow chart model that outlines the end-to-end steps of a planned business process.
  • Systems Modelling Language (SysML): Supports the analysis, design, and verification of complex systems, including software, hardware, information, procedures, personnel, and facilities in a graphical notation.
  • Architectural design: Describes the views, models, behavior, and structure of the system.
  • Logical design: Represent the inputs, data flow, and outputs of the system. For e.g., entity-relationship (ER) diagrams.

Advantages of system design interviews

1. Holistic skill assessment: These interviews assess a candidate's ability to design, plan, and articulate complex systems, going beyond basic coding skills.2. Evaluating architectural knowledge: They are crucial for roles requiring knowledge of system architecture, allowing interviewers to gauge a candidate's proficiency in this area.3. Testing problem-solving in real-world scenarios: System design interviews often involve real-world problems, testing how candidates approach practical challenges.4. Identifying big-picture thinking: They help identify candidates who can think strategically about system scalability, maintenance, and efficiency.5. Encouraging clear communication: Candidates must articulate their thought process clearly, demonstrating their communication and collaboration skills.

Why are system design interviews important?

Today, most tech companies invest in building scalable, high performant systems. Hence, it's essential for candidates to have impeccable design skills. The purpose of a system design interview is to go beyond the standard data structures and algorithm questions. You can see what candidates think about operational scenarios, edge cases, limitations, and assumptions.

System design interviews are intentionally open-ended. Through system design interviews, an interviewer can evaluate a candidate along different dimensions. It also helps to analyze a candidate's overall thought process, thinking, knowledge of end-to-end systems, and communication skills. However, we all know how hard it can be to conduct system design interviews even on a video call. While one can use a collaborative document like Google Docs to create diagrams and flowcharts, the process can be extremely tedious and result in poor candidate experience.

Integrating draw.io in HackerEarth FaceCode

To help you migrate to a completely remote hiring process, we have integrated draw.io to FaceCode. This allows you to effortlessly conduct system design interviews by letting developers create block diagrams and architecture designs in a live interview. Thus, interviewers can evaluate a developer's system design, problem-solving, and role-specific skills.

The draw.io editor provides a large variety of libraries to choose symbols from. Candidates can draw ER diagrams, network diagrams, mindmaps, wireframes, Venn diagrams, flowcharts, etc. You can select any category based on your requirement for candidates to answer system design questions.

Let's consider an example: you want to test your candidates on AWS/Analytics using the draw.io. editor.

You can go to the general set of shapes on the left, collapse it, and expand the AWS/Analytics set of shapes.

AWS/Analytics shapes

The editor will provide your candidate with a complete set of tools for drawing AWS/Analytics diagrams.

The candidate is required to drag an entity shape on the drawing canvas at the center and streamline their thought process into diagrams or system designs.
