Best Interview Questions to Ask Candidates

Key takeaways

• Behavioral questions (“tell me about a time…”) produce more reliable signal than hypothetical ones.
• The strongest interviews are built around a small number of job-relevant dimensions, not a generic question bank.
• Assessment results before the interview help you decide which dimensions to probe deepest.
• Follow-up questions matter more than the opening question — push for specifics, not summaries.
• Score answers against the same criteria for every candidate to keep comparisons fair.

Why the right questions matter

Most interviewers ask questions that feel natural rather than questions that predict performance. Broad prompts like “tell me about yourself” or “what’s your biggest weakness” rarely surface information that separates a strong hire from a weak one. Candidates who interview well aren’t always candidates who perform well — the gap between the two is exactly what a structured question set is designed to close.

The fix is to anchor every question to a specific, job-relevant ability, and to ask for a real example rather than a general opinion. “Tell me about a time you had to manage several competing deadlines” produces far more useful information than “how do you handle pressure?”, because the candidate has to describe something that actually happened rather than a version of themselves they’d like you to believe.

A framework for choosing questions

1. Start from the role’s two or three core abilities. Build every question around one of them.
2. Use assessment results to prioritize. If a candidate’s attention-to-detail score suggests a gap worth checking, lead with that.
3. Ask for a specific, real example. “Walk me through a time when…” beats “how would you…”.
4. Follow up for detail. What exactly did they do? What was the outcome? What would they change?
5. Score consistently. Use the same rubric across candidates for the same role.

Examples

Problem-solving: “Tell me about a time you identified a problem before anyone asked you to look into it. What did you do, and what happened?”

Communication: “Describe a time you had to explain something complicated to someone without your background. How did you adjust your explanation?”

Attention to detail: “Tell me about a time you caught an error others had missed. How did you find it?”

Assessments to use

Pair these questions with assessment results to know where to focus interview time:

• General Cognitive Ability — reasoning and problem-solving under time pressure.
• Communication Skills — written and verbal clarity.
• Attention to Detail — accuracy under competing instructions.
• Leadership Potential — decision-making and team influence.

Role-specific considerations

Interview questions work best when they’re tailored to the role, not generic across the company. See our 21 role-specific hiring guides for ready-made assessment combinations and interview angles by position.

Connecting results to the interview

Treat a moderate or low assessment result as an interview prompt, not a disqualifier. If a candidate’s cognitive ability result suggests reasoning speed under pressure is worth checking, build a question around exactly that scenario instead of asking something unrelated.

Common mistakes

• Asking hypothetical questions. “What would you do if…” is easier to answer well without having actually done it.
• Using the same questions for every role. A generic bank misses what actually matters for the job.
• Not following up. The first answer is rarely the most informative one.
• Ignoring assessment results when planning questions. They tell you exactly where to dig.

Frequently asked questions

How many interview questions should I ask?

Quality matters more than quantity. Five to seven well-chosen, role-relevant questions with real follow-up usually beat fifteen surface-level ones.

Should every interviewer ask the same questions?

For the core, role-relevant questions, yes — it keeps the comparison across candidates fair. Interviewers can still add their own follow-ups.

Are behavioral questions better than hypothetical ones?

Generally yes. Past behavior in a specific situation is more predictive than a hypothetical response.

How do assessments change what I should ask?

They tell you which dimensions are worth the most interview time for a specific candidate, rather than guessing.

Can I reuse the same interview questions across roles?

Only the general framework. The specific questions should map to the abilities that matter for each role.
