Learn how to effectively assess technical skills in candidates, ensuring better hiring decisions and greater team productivity.
Hiring developers can be tough - 73% of technical hires underperform compared to their interview results. Mis-hires lead to costly delays, extra workload for existing teams, and project setbacks. To avoid this, you need a structured approach to evaluate both technical and soft skills effectively.
Here’s how to ensure your hiring process identifies the right talent:
- Define the skills you need: Work with your engineering team to pinpoint must-have vs. nice-to-have skills.
- Use a skill matrix: Organize technical requirements, proficiency levels, and assessment methods for clarity.
- Choose effective testing methods: Combine live coding interviews, take-home projects, automated tools, and portfolio reviews to get a full picture of a candidate’s abilities.
- Leverage metrics: Track time-to-hire, assessment completion rates, and employee performance to refine your process.
Accurate skill assessment ensures better hiring decisions, reduces risks, and keeps your team productive.
Identifying the Technical Skills You Need
To build a strong team, you need to pinpoint the exact technical skills required for the role. This starts with understanding your team's unique challenges. Without their input, you risk focusing on skills that look impressive but don’t align with actual needs. The goal is to identify the expertise necessary to tackle your team’s specific technical hurdles.
The best way to approach this? Work closely with your engineering teams. These leaders know the technical details that can make or break performance in their environment.
Working with Engineering Teams
Collaborating with engineering leaders is key to identifying the technologies and technical requirements that are part of the team’s daily workflow. For instance, does the role demand advanced database optimization skills, or is basic SQL knowledge enough?
Set up focused discussions with hiring managers and senior engineers to clarify the immediate technical challenges the team faces. Together, you can outline the tools, frameworks, and experience levels required for the role. Is deep Python expertise critical for a backend engineer, or is it more important to have API design experience? Differentiating between must-have and nice-to-have skills ensures you assess candidates on what truly matters, rather than unintentionally filtering out strong prospects.
Engineering teams also provide insight into their development practices. A team that uses test-driven development will prioritize different skills than one focused on rapid prototyping. These details help you evaluate not just technical ability but also alignment with the team’s processes and working style.
Building a Skill Matrix
After gathering input, organize everything into a skill matrix - a structured framework that links technical requirements to specific assessment methods. This approach makes your evaluation process more organized and fair.
In your matrix, categorize skills by their importance and the level of proficiency required. For example, database expertise might involve crafting complex queries for one role, while another might only need a basic understanding of relationships. Be clear about what “proficiency” looks like for each skill in the context of the role.
Include both hard skills (like programming languages, frameworks, and tools) and technical soft skills (such as debugging, architectural thinking, and technical communication). Then, arrange these skills by how easily they can be verified and the time required to assess them. This helps you create efficient workflows that respect both the candidate’s and the interviewer’s time.
Finally, keep your skill matrix up to date. Technology evolves quickly, and what was crucial six months ago might no longer be relevant. Regular check-ins with engineering teams ensure your assessments remain current and effective. By maintaining this clear and structured framework, you’ll create a foundation for consistent and efficient technical evaluations across the board.
Effective Methods for Testing Technical Skills
Once you've built a clear skill matrix, the next step is choosing assessment methods that truly measure each technical requirement. A mix of approaches often works best, giving you a well-rounded view of a candidate's capabilities. Below are some effective strategies to evaluate the skills outlined in your matrix.
Live Technical Interviews
Live coding interviews are a great way to assess a candidate’s problem-solving abilities, how they perform under pressure, and how well they communicate technical concepts. Unlike written tests, these sessions let you see their thought process in action.
Focus these interviews on real-world scenarios instead of abstract puzzles. For example, if you're hiring a backend developer, ask them to design an API endpoint or debug a database query. This gives you a better sense of how their skills align with the job’s actual demands.
Keep the sessions concise - 45 to 60 minutes is usually enough to evaluate key skills without overwhelming the candidate. Let them use their own tools to work in a way that feels natural to them.
Pay close attention to how they explain their reasoning. Strong candidates will articulate their approach, ask clarifying questions, and weigh the pros and cons of different solutions. These communication skills are often just as important as technical expertise, especially in team settings.
Take-Home Coding Projects
While live interviews test quick problem-solving, take-home projects provide a deeper look at a candidate’s coding abilities over a longer period. These assignments often result in higher-quality work since candidates can complete them in a more relaxed environment.
Design take-home tasks that reflect real job scenarios and can be completed in 2-4 hours. Be transparent about the time commitment and provide clear instructions, including preferred tools or technologies. However, allow some flexibility so candidates can highlight their strengths.
For instance, instead of asking for a basic to-do app, you might request something like "build a simple inventory tracking system" or "design an API to process customer feedback." Assignments like these give candidates a chance to demonstrate practical problem-solving skills.
It’s important to avoid asking candidates to work on actual company projects or features you plan to use. This ensures ethical boundaries are respected and shows appreciation for their time and effort.
Automated Technical Screening Tools
Automated screening platforms provide a fast and consistent way to evaluate large numbers of candidates. These tools are particularly useful during the initial stages of the hiring process, helping you identify promising candidates before investing in more personalized assessments.
Modern tools can test a wide range of skills, from coding and system design to technical problem-solving. They use standardized criteria, which helps minimize bias and ensures a consistent evaluation - especially helpful when multiple team members are involved in hiring.
However, these tools should complement, not replace, human judgment. While they excel at assessing technical skills, they can’t evaluate communication, creativity, or team fit. Think of them as a way to narrow down your candidate pool rather than make final decisions.
Look for platforms that provide detailed feedback reports instead of just pass/fail results. This additional insight helps you tailor follow-up interviews and better understand each candidate’s strengths and weaknesses.
Portfolio and Open-Source Code Reviews
Reviewing a candidate’s existing work can offer valuable insights into their real-world coding habits and long-term project skills. Portfolios and open-source contributions often reveal more about their abilities than theoretical assessments.
When evaluating portfolios, focus on practical evidence of problem-solving, creativity, and analytical thinking. Pay attention to how their code is organized, the quality of documentation, and how they’ve tackled complex challenges.
Open-source contributions are another goldmine of information. Look at their commit history, pull request discussions, and how they respond to feedback. These interactions show not only their technical skills but also their ability to collaborate within a team.
If a candidate doesn’t have a formal portfolio, consider smaller projects, team contributions, or internal tools they’ve worked on. The quality of their thinking and execution often matters more than the scale of their work.
| Method | Signal Quality | Scalability | Candidate Experience | Implementation Complexity |
|---|---|---|---|---|
| Portfolio Reviews | High | Medium | High | Low |
| Live Coding Sessions | High | Low | Medium | Medium |
| Take-Home Projects | High | High | Varies | Low |
| Technical Discussions | Medium | Medium | High | Low |
| Automated Assessments | Medium | Very High | Low-Medium | High |
| Pair Programming | Very High | Low | High | Medium |
If a candidate lacks an extensive portfolio, don’t discount them. Smaller projects or personal experiments can still demonstrate their skills and potential. Often, the way they think and approach problems is more telling than the size or complexity of their work.
