Evaluating candidates with technical interview questions demands clear focus and realistic benchmarks. The questions must reveal relevant skills quickly and accurately, reflecting actual job challenges, for IT interview questions. Here’s a direct, no-nonsense four-step method to build questions that deliver reliable insights without wasting time or adding hidden risks.

Brainstorming with the A-Team: Assemble Diverse Brainstorming Teams

Pull together contributors from across your engineering ecosystem—senior developers, managers, product folks, HR, even customer service. This mix surfaces both technical expertise and essential soft skills.

• Why diversity matters: Purely technical questions miss real workplace dynamics. Non-engineers highlight how candidates must collaborate, communicate, and problem-solve beyond code.
• Routine cadence: Set regular brainstorming meetings that review current projects, skill gaps, and known pain points. Use real cases, not abstract puzzles, to keep questions grounded.

Checklist for effective brainstorming:

• Include stakeholders familiar with the role’s daily demands.
• Share specific, recent problem examples from workflows.
• Cover technical skills plus communication and teamwork.
• Prioritize questions mirroring actual job challenges to lower risk of mismatch.

The three U’s of a good question: Ensure Questions Are Clear, Unambiguous, and Useful

Every question must meet three simple but critical criteria—what I call the "Three Us":

1. Understandable: Candidates and interviewers get what’s asked immediately—no guesswork.
2. Unambiguous: Experts independently reach the same solution without debate.
3. Useful: It tests skills directly tied to the role and tasks candidates will face.

For structured tests, strict unambiguity avoids grading inconsistencies. In live interviews, slight ambiguity can spark useful discussions—but only if intentional and manageable.

Internally test and validate questions

Don’t run questions blind on candidates. Pilot internally with engineers, product stakeholders, and future interviewers. Testing cuts bias and confirms that questions measure what matters.

Two roles during validation:

• Test taker: Approach questions like candidates. Flag unclear wording, misfit difficulty, and realism of the problem.
• Reviewer: Judge if the question truly separates skill levels and aligns with job needs.

Focus validation on:

• Clear language that avoids confusion.
• Close relevance to role and company.
• Candidate experience—don’t irritate or drain them unnecessarily.

Refine or drop questions based on this feedback. Save time, money, and reputation by vetting questions up front.

Monitor candidate feedback and analyze candidate data for continuous improvement

After you deploy questions, the work isn’t over. Monitor key metrics and candidate input to keep your interview process sharp and fair.

Track these:

• Success rate: Watch pass/fail balance. Too many fails equals unrealistic or confusing questions. Too many passes signals questions that are too easy.
• Completion time: Large timing outliers mean the question or clarity needs adjusting.
• Response variety: Wide answer spread often points to ambiguity or instructions missed.

Collect direct feedback via post-assessment surveys and open comment fields. Candidates will flag unclear or unfair prompts.

Use this data in regular reviews with your question owners and stakeholders. Tune clarity, difficulty, or relevance constantly. Remove obsolete questions quickly to speed throughput and lower risk.

Technology request system for updated assessments

Tech shifts fast. Your questions must keep pace or become liabilities.

• Stay current by tracking industry trends, reading reliable tech sources, and reviewing internal projects.
• Invite engineering teams regularly to propose new topics or skills for evaluation.
• Formalize updating the question pool with these insights—don’t wait for crises.

This way, your assessments stay sharp, testing what matters for today and tomorrow’s demands.

FAQ
