The Top 6 Interviewing Techniques for Technical Skill Assessment

Technical skill assessment becomes more effective with a well-laid-out approach that blends traditional and modern methods. Here are six interview techniques that help organizations find the best technical talent:

1) Define Clear Evaluation Criteria

The foundation of an effective technical interview is a well-defined evaluation framework. Before conducting an interview, it is essential to outline the key skills required for the role, such as programming proficiency, debugging capabilities, problem-solving ability, and system optimization skills. This ensures that interviewers assess candidates consistently based on relevant competencies rather than subjective impressions.

Using a structured scoring system can help eliminate bias and improve hiring accuracy. Each candidate’s performance can be rated based on predefined metrics such as code efficiency, correctness, scalability, and adaptability to real-world scenarios. Weighting different skills appropriately based on job role requirements ensures a fair comparison between candidates.

2) Use a Mix of Interview Formats

A variety of interview formats can provide a well-rounded assessment of a candidate’s technical abilities:

• Live Coding Challenges: These real-time coding exercises test a candidate’s logical thinking, problem-solving speed, and ability to work under pressure. Interviewers can observe how candidates approach problems, write code, and debug in real time.
• Pair Programming: This collaborative technique evaluates how well a candidate works in a team. It helps assess code quality, problem-solving approach, and communication skills as they work alongside an interviewer on a shared coding task.
• Behavioral Interviews: While technical skills are crucial, a candidate’s ability to think critically and adapt to challenges is equally important. Behavioral interviews focus on real-life problem-solving experiences, often using the STAR (Situation, Task, Action, Result) method to assess a candidate’s approach to challenges in past roles.

3) Ask Open-Ended and Problem-Solving Questions

Rather than focusing on simple technical questions, open-ended problems allow candidates to demonstrate their logical thinking, creativity, and structured problem-solving approach. Instead of expecting just a correct answer, interviewers should assess the candidate’s thought process, efficiency, and ability to optimize solutions.

Questions like:

• How would you optimize a database query handling millions of records?
• Explain how you’d debug a memory leak in a C++ application.
• Design an algorithm to find duplicate elements in a list efficiently.

Such questions encourage candidates to break down problems systematically, articulate their thought processes, and explore different approaches.

4) Use Ground Scenarios

Using real-world technical scenarios provides a more practical assessment of a candidate’s ability to handle tasks they will face in the job. Instead of theoretical questions, candidates can be given case studies or system design problems that mimic actual workplace challenges.

For example, a frontend developer may be asked to optimize a web page’s load time, while a backend engineer may need to design a scalable API for a high-traffic application. Real-world tasks not only help assess technical expertise but also reveal a candidate’s problem-solving approach, debugging skills, and architectural knowledge.

5) Look at Soft Skills Among Technical Abilities

Technical interviews should not solely focus on coding skills. A successful engineer must also possess strong communication, adaptability, and teamwork skills. Candidates should be assessed on how well they explain their solutions, justify trade-offs, and collaborate with teams.

Using behavioral interview techniques like the STAR method, interviewers can evaluate how candidates approach complex problems in real-world situations. Sample behavioral questions include:

• Tell me about a time you faced a major bug in production and how you handled it.
• Describe a situation where you had to work with a difficult team member on a technical project.

These questions provide insight into how candidates handle pressure, communicate solutions, and adapt to unexpected challenges.

6) Employ AI-Based and Automated Assessment Tools

AI-driven assessment platforms can streamline the technical interview process by providing objective, data-driven insights into a candidate’s skills. Platforms like HackerRank, Codility, LeetCode, and CodeSignal enable recruiters to:

• Evaluate coding efficiency and correctness using automated grading.
• Analyze code quality and optimization techniques using AI-based assessments.
• Generate reports on a candidate’s strengths and weaknesses based on predefined benchmarks.

By integrating AI tools, companies can reduce bias, speed up the hiring process, and ensure that assessments remain consistent and scalable.

Companies using AI-based technical assessments need 40% less time for onboarding, and their candidates show 60% better problem-solving skills compared to traditional methods.

 Common Mistakes to Avoid in Technical Interviews

1) Over-Reliance on Tricky Algorithmic Questions Unrelated to the Job

One of the biggest pitfalls in technical interviews is focusing too much on complex algorithmic puzzles that have little relevance to the actual job. While questions on data structures and algorithms (DSA) are essential for assessing problem-solving skills, many real-world roles don’t require daily use of advanced algorithms like graph theory or dynamic programming.

For example, a front-end developer is unlikely to use Dijkstra’s algorithm in their daily work, so testing them on it rather than JavaScript frameworks or UI development skills is ineffective. Similarly, DevOps engineers rarely need to implement merge sort from scratch but must understand CI/CD pipelines and infrastructure automation.

Instead of relying on abstract puzzles, interviewers should focus on practical coding assessments related to the role. Asking candidates to build a small feature, debug code, or optimize a slow query provides a much better measure of their skills.

2) Not Considering Real-World Project Experience

Another common mistake is overlooking a candidate’s actual project experience in favor of theoretical knowledge. A candidate who has built scalable applications, worked with production systems, or contributed to open-source projects often brings more practical value than someone who excels at algorithmic challenges but lacks hands-on experience.

For example, a backend developer with experience in database optimization, API design, and security best practices is likely more valuable than someone who merely knows how to reverse a linked list. Similarly, a mobile app developer who has built and deployed real-world apps should be assessed on framework expertise (React Native, Flutter, Swift, or Kotlin) rather than theoretical knowledge of mobile architecture.

Interviewers should ask questions about past projects, such as:

• What was the most challenging bug you encountered in a project, and how did you fix it?
• How do you ensure the scalability of your applications?
• Can you walk us through a performance optimization you implemented?

By focusing on real-world skills, debugging abilities, and project experience, companies can hire engineers who are job-ready rather than just good at theoretical tests.
