Most "interview question lists" are noise — 200 LeetCode problems no recruiter could grade. This isn't that. These are the questions that produce signal in a 15-minute conversation, organized so you can pull the right one at the right moment.
The Question Framework
Every good technical screen has three movements: warm up the candidate so they actually talk, probe for depth so you separate fluency from familiarity, and test seniority by handing them ambiguity. The questions below map to those three jobs. Pick two from each bucket and you have a defensible 15-minute screen.
Warm-Up Questions (First 3 Minutes)
The goal here is to get the candidate talking confidently about something they've actually built. Strong candidates light up. Weak ones get vague.
- "Walk me through the last production bug you shipped a fix for. What was the signal that something was wrong?"
- "Tell me about a system you built that you'd architect differently today. What changed your mind?"
- "What's a piece of your stack you'd rip out if you could? Why?"
- "Describe a code review where you pushed back. What was the disagreement about?"
Depth Probes (Minutes 4–10)
Pick the stack from their resume and go one layer deeper than the buzzword. Fluent candidates will keep going; surface-level ones will stall around the second follow-up.
- Frontend: "What's the difference between useMemo and useCallback, and when have you actually needed either?"
- Backend: "When would you reach for a queue instead of a direct API call? What breaks if you choose wrong?"
- Data: "Walk me through what happens when a query gets slow. Where do you start looking?"
- Infrastructure: "Describe a time you debugged a production issue that turned out to be a network problem. How did you isolate it?"
Seniority Signals (Final 5 Minutes)
This is where you separate strong individual contributors from people who can lead. Hand them ambiguity and watch what they do with it.
- "You're handed a service that's been on fire for two weeks. Where do you start?"
- "A junior engineer on your team keeps shipping bugs. What's your first conversation with them?"
- "You disagree with your tech lead on an architectural decision. The team is watching. What do you do?"
When to Stop Asking and Automate
These questions work — but if you're running 30+ first-round screens a week, even the best human interviewer drifts. Different recruiters ask different questions. Different days produce different rubrics. An AI interviewer like Talia runs the same conversation with every candidate, generating a comparable scorecard each time. That consistency is the actual moat at scale. Pair it with a defensible scorecard and you have a screening operation that won't break under volume.
