Tell me about a time you had to explain a technical problem or trade-off to someone non-technical. How did you make it land?

What the interviewer is looking for

  • This question tests communication. Explains technical ideas in terms the listener cares about, checks for understanding, and uses concrete examples rather than jargon.
  • What to bring out: Framing in terms of the listener's goals, plain language and analogies, offering options with trade-offs, and checking they understood.
  • Expect a follow-up like: How did you know your explanation worked?

Another way it may be asked: Say a product manager asks why a feature will take three weeks instead of three days. How would you explain it?

A structure to follow: STAR, with the weight on Action and Result

  1. Step 1

    Situation

    One or two sentences: where, when and what was at stake. Pick a real example you were close to.

  2. Step 2

    Task

    What you personally were responsible for. Say "I", not only "we", so the communication you showed is visible.

  3. Step 3

    Action

    The two or three things you did and why you chose them over the alternatives. This should be about half your answer.

  4. Step 4

    Result

    What changed, in your own measure of it, and what you would do differently. Only use numbers you can stand behind.

This is guidance on shape, not a script. Use your own real experience and facts; never invent details to fill a gap. See the STAR guide and answer frameworks.

Common slips

  • Describing what the team did without saying what you did.
  • Choosing an example with no clear outcome, or one you cannot answer detailed questions about.
  • Ending on the action and skipping the result and what you learned.

How to practise it

Write two bullet points for each STAR letter, then say the answer aloud in about two minutes.
