What to Ask as an Interviewer and What to Avoid

The questions you ask in an interview determine the quality of the hire you make. Strong questions reveal how a candidate actually works, thinks, and solves problems. Weak questions get rehearsed answers that tell you almost nothing. Whether you’re interviewing for the first time or tightening up your process, the right mix of behavioral, role-specific, and probing questions will give you far more signal than a casual conversation ever could.

Behavioral Questions That Reveal Real Performance

Behavioral questions ask candidates to describe specific past situations rather than hypothetical ones. The logic is simple: how someone handled a challenge before is the best predictor of how they’ll handle one again. These questions typically start with “Tell me about a time when…” or “Give me an example of…” and they force candidates past generic claims like “I’m a great communicator” into concrete stories with details you can evaluate.

A strong behavioral question targets a skill or trait the role actually demands. If the job requires cross-functional collaboration, ask: “Describe a situation where you had to collaborate with someone who had a very different working style. What did you do, and how did it turn out?” If it requires working under pressure: “Tell me about a time your team had to meet a tight deadline. How did you make sure the work got done on time?” If leadership matters: “Give me an example of how you’ve motivated others when energy or morale was low.”

Other high-value behavioral questions include:

  • “Tell me about a time you made a mistake at work. How did you fix it?”
  • “Talk about a time you had to manage several projects at once. How did you prioritize?”
  • “When have you had to convince others to see a situation from your perspective? Walk me through how you did it.”
  • “Give me an example of a time you adapted to a major change at work.”

What you’re listening for isn’t a perfect outcome. You’re listening for self-awareness, clear thinking, and the ability to describe their own role honestly. Candidates who take ownership of failures and explain what they learned are usually stronger hires than those who only tell success stories.

Role-Specific Questions That Test Real Skills

Behavioral questions tell you how someone works. Role-specific questions tell you whether they can do this particular job. These should be tailored to the actual responsibilities listed in the job description, not generic “Where do you see yourself in five years?” filler.

If you’re hiring a project manager, ask how they’ve handled scope creep or competing stakeholder priorities. If you’re hiring a marketer, ask them to walk you through a campaign they built, what worked, and what they’d change. If the role involves data, give them a scenario: “You’re looking at a report and the numbers don’t match what you expected. Walk me through how you’d investigate that.”

For roles where technology proficiency matters, you can ask candidates how they use specific tools in their workflow. If the position involves working with AI tools or automation, a straightforward question like “Tell me about a project where you used AI or automation to solve a problem” will quickly separate candidates who have hands-on experience from those who’ve only read about it. A follow-up like “How do you stay current with new tools in your field?” reveals whether someone is genuinely curious or just checking a box.

Questions That Assess What a Candidate Adds

Many interviewers default to evaluating “culture fit,” which often just means hiring people who feel familiar. A better frame is culture add: what unique perspective, skill, or experience does this person bring that your team doesn’t already have?

Three questions work well here:

  • “How do your colleagues benefit from working with you specifically, as opposed to someone else on your team?”
  • “Tell me about a time when understanding someone else’s perspective helped you accomplish a task or resolve an issue.”
  • “What’s your impression of our company’s culture and values? How do you think we could improve?”

The last question is especially revealing. Candidates who can articulate a thoughtful critique of your organization have done their homework and are confident enough to be honest. That combination usually signals someone who will push the team forward rather than just blend in.

How to Probe When Answers Are Vague

Candidates will sometimes give surface-level answers, either because they’re nervous or because they don’t actually have the experience they’re claiming. Your job as the interviewer is to dig deeper without making it feel like an interrogation.

When a candidate gives a vague response, ask for specifics. “Can you walk me through that step by step?” or “What was your specific role in that project?” will often separate someone who led the work from someone who was loosely involved. If a candidate says they “helped improve a process,” ask what the process looked like before, what they changed, and what the measurable result was.

Other useful follow-ups:

  • “What would you do differently if you faced that situation again?”
  • “Who else was involved, and how did you divide the work?”
  • “What was the hardest part of that, and why?”

Don’t rush past an answer that doesn’t quite land. A brief pause after a candidate finishes speaking often prompts them to elaborate naturally. And if something sounds rehearsed, redirect with a related but unexpected angle: “That’s helpful. Now tell me about a time that approach didn’t work.”

Questions That Give Candidates a Chance to Interview You

The best interviews are two-directional. You’re evaluating the candidate, and the candidate is evaluating you. Leaving room for their questions isn’t just polite; it’s informative. What a candidate asks tells you what they care about.

Near the end of the conversation, try something more specific than “Do you have any questions for me?” Instead, prompt with: “What would you need from this role or this team to do your best work?” or “What’s something about this position that you’d want more clarity on before making a decision?” These invitations tend to surface real concerns, like management style, growth paths, or workload expectations, that a generic prompt might not.

Pay attention to whether their questions focus on contribution (“How does the team handle feedback?”) or entitlement (“How quickly can I get promoted?”). Neither is disqualifying on its own, but the pattern tells you something about their priorities.

Questions You Should Never Ask

Federal law prohibits employment discrimination based on race, color, religion, sex, national origin, age, disability, and genetic information. The EEOC recommends avoiding questions about any of these protected characteristics entirely, because even well-intentioned questions can be used as evidence of discriminatory intent if a hiring complaint is filed.

Avoid asking about:

  • Religious practices (“Which church do you attend?”)
  • Family status or plans (“Do you plan to have children?”)
  • Age, unless there’s a legal minimum for the role
  • National origin or ethnicity (“What language do you speak at home?”)
  • Disabilities or medical conditions
  • Marital status, pregnancy, or childcare arrangements

The simplest rule: if the question isn’t directly related to whether the candidate can perform the job’s duties, don’t ask it. If you need to verify that someone meets a legal age requirement or can work specific hours, frame it around the job’s actual requirements (“This role requires availability on weekends. Does that work for you?”) rather than personal circumstances.

Structuring the Interview for Better Results

Asking great questions in a disorganized interview still produces unreliable results. Use the same core set of questions for every candidate applying to the same role. This gives you a consistent basis for comparison and reduces the influence of gut feelings or personal rapport.

A practical structure for a 45-minute to one-hour interview:

  • First 5 minutes: Brief introductions and an overview of the interview format so the candidate knows what to expect.
  • Next 15 minutes: Two or three behavioral questions targeting the role’s most important soft skills.
  • Next 15 minutes: Two or three role-specific or technical questions that test job-relevant knowledge.
  • Next 5 minutes: One or two culture-add questions.
  • Final 10 minutes: Candidate’s questions and a clear explanation of next steps and timeline.

Take notes during the interview or immediately after. Memory is unreliable, especially if you’re interviewing multiple people in a day. Write down specific things the candidate said, not just your impression of them. When you sit down later to compare candidates, those notes will be far more useful than a vague sense of who “seemed good.”
