What the interviewer is looking for

  • This question tests stakeholder management. Clarifies requests, sets expectations on timing, handles challenges to numbers calmly and builds trust over time.
  • What to bring out: Stays calm, reconciles definitions and sources, owns any mistake and explains the difference clearly.
  • Expect a follow-up like: How did that change how you prepare reports now?

Another way it may be asked: A director says your report is wrong because their own figure is different. What do you do?

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 stakeholder management 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.
