The questions
- 01 · Behavioral
Tell me about yourself.
Why interviewers ask this: For a tech lead, this is your 60-second pitch. The interviewer is screening for clarity, signal, and fit.
How to answer: Use a Past → Present → Future structure: 1 sentence on background, 1–2 on current scope and a relevant win, 1 on why you want this role.
- 02 · Cultural Fit
Why are you interested in this role?
Why interviewers ask this: They are checking that you have read the JD and understand what makes this role and company different from generic alternatives.
How to answer: Tie 2 specific aspects of the role (a project, a stack, a customer segment) to 2 things you have actually done. Avoid flattery.
- 03 · Behavioral
Tell me about a time you failed.
Why interviewers ask this: Interviewers want to see how you handle real situations using the STAR method (Situation, Task, Action, Result).
How to answer: Pick a real failure with measurable consequences. Spend most of the answer on what you learned and the change you made afterward.

How do you split your time between coding and leading?
Why interviewers ask this: Universal tech-lead trap.

A senior engineer disagrees with your direction. How do you handle it?
Why interviewers ask this: Tests influence, ego control, and conflict resolution.

Walk me through a project that slipped on your watch.
