Tell me about a time you noticed something frustrating for users that nobody had asked you to fix. What did you do?

What the interviewer is looking for

  • This question tests user focus. Talks about real user pain, notices rough edges unprompted, and uses feedback or data to guide improvements.
  • What to bring out: Specific user pain, evidence such as feedback or analytics, taking initiative appropriately, and checking the fix actually helped.
  • Expect a follow-up like: How did you balance that against the work you were already assigned?

Another way it may be asked: Maybe a confusing error message or a slow button. What did you notice and how did you get it improved?

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 user focus 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.
