Describe something you improved that nobody asked you to improve. How did you get other people to care about it?
What they are really testing: This tests whether you can build a case and win consent, not just whether you can code. Unasked improvements die without a story and an ally.
A real interview question
Describe something you improved that nobody asked you to improve. How did you get other people to care about it?
What most people say
drag me
“I refactored a lot of our old code because it was really messy and nobody had cleaned it up. It is much nicer now.”
Nicer is not a result, and a refactor with no user, no metric, and no supporter is indistinguishable from personal preference.
The follow-ups they ask next
How do you stop it going stale again in a year?
Tie the update to an existing ritual, for example the postmortem template requires touching the runbook entry.
Was this the highest value thing you could have worked on?
Be honest, compare it against your sprint work and explain the time you actually spent, do not pretend it was free.
What the interviewer is listening for
- Gathered evidence before pitching
- Shipped the smallest useful slice, not the dream version
- Found an ally and made yes cheap
- Has a plan for it not decaying again
What sinks the answer
- Improvement was purely aesthetic taste
- No measurement before or after
- Did it alone and nobody else adopted it
- Cannot explain who was actually hurting
If you genuinely do not know
Say this instead of freezing. Reasoning out loud from what you do know beats silence every single time, and a good interviewer is listening for exactly that.
“I have not driven an unasked improvement end to end, but here is how I would approach it: I would spend a few weeks logging the pain in numbers, then pitch the smallest slice that fixes most of it to whoever feels the cost.”
