Building a Better Interview Question Set
I've spent years refining how we screen candidates, and honestly, most teams get it wrong on day one. They grab questions from a generic list and expect consistency. It doesn't work. The real problem isn't finding good Interview Questions—it's designing a system where different interviewers reach the same conclusion about a candidate without colluding beforehand. Let me explain what actually works from my own experience.
Structure Your Interview Questions Around Competencies, Not Topics
Most people organize questions by subject area—leadership, technical skill, communication. That's fine on paper. In practice, you end up with a conversation that wanders and leaves you unable to compare Candidate A against Candidate B fairly. The way around this is to start with competencies. Define exactly what traits matter for the role, then map each question directly to one trait. If a question doesn't tie to a competency, cut it. I once ran a round of hiring where we spent twenty minutes discussing a candidate's "passion for learning" with no scoring rubric attached. We couldn't compare that candidate to anyone else because nobody had written down what "passionate" actually looks like at different levels. That interview produced zero usable data. Here's the process I use now: Step one: List the top five competencies for the role. Be specific. "Good communicator" is useless. "Explains complex technical decisions to non-technical stakeholders in under three minutes" is something you can score.
Step two: Write two questions per competency. One behavioral—"Tell me about a time when..."—and one situational—"What would you do if..." Behavioral questions predict past performance. Situational questions reveal problem-solving approach. Use both because they catch different failure modes. Step three: Build a scoring rubric with four levels for each competency. I use 1 through 4. A score of 1 means the candidate gave a vague answer with no concrete example. A score of 4 means they demonstrated the competency clearly with evidence. Most interviewers skip this step and just remember whether they "liked" the person. That's how biased hiring happens.

Common Pitfalls That Sink Your Interview Questions
The biggest mistake I see is asking leading questions disguised as open-ended ones. "You're comfortable with agile methodologies, right?" is not a question. It's confirmation bias with a question mark. Candidates will tell you what they think you want to hear if you give them the slightest hint about the answer. I learned this the hard way when a candidate I rated a 4 on collaboration turned out to be difficult to work with within six weeks. The question I'd asked was "Tell me about a time you resolved a conflict with a teammate." The candidate gave a polished story about a disagreement where they were clearly the reasonable one. I never asked about their role in creating the conflict in the first place. Now I always follow up with "What part did you play in starting the disagreement?" It takes an extra thirty seconds and exposes people who blame others for everything. Another pitfall is asking too many questions in one interview. I used to run ninety-minute panels where we fired off twelve or thirteen questions. By question eight, everyone was performing on autopilot. The candidate was too tired to dig deep, and we were too distracted to listen carefully. I cut the count to six solid questions with follow-ups. Our hiring accuracy improved noticeably because we were actually paying attention instead of checking boxes.
When This Approach Breaks Down
Competency-based Interview Questions don't work well for entry-level roles where candidates genuinely lack experience to draw from. A college graduate hasn't led a team through a crisis. Forcing behavioral questions on them produces shallow answers that look worse than they are. In those cases, lean heavier on situational questions and work samples. Give them a realistic task and evaluate the output directly. It's faster and more accurate for junior positions. The system also requires discipline. If interviewers skip the rubric because they're rushing, you're back to gut feelings. I've seen teams abandon structured interviews after one bad round where the hiring manager felt the process was "too rigid." Structured interviewing feels rigid because it replaces intuition with evidence. That discomfort is the point. If it feels easy and natural, you're probably not doing it right.
A Quick Resource
If you want a starting point, I've put together a template with sample Interview Questions organized by common competencies across engineering, product, and operations roles. It includes the scoring rubrics and follow-up prompts. You can download it here. It won't solve your hiring problems on its own. But it'll save you from reinventing the wheel every time you need to hire someone.
