Tell me about an outage or broken deploy you were involved in. What did you do in the moment, and what did you change afterwards?

What the interviewer is looking for

  • This question tests ownership. Takes responsibility for outcomes, follows incidents through to lasting fixes, and owns mistakes without blaming others.
  • What to bring out: Owned their part honestly, restored service first, communicated status, and drove lasting fixes rather than a one-off patch.
  • Expect a follow-up like: How did you make sure the follow-up actions actually got done?

Another way it may be asked: Think of a time something you touched broke production. Walk me through how you handled it then and after.

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 ownership 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.
