Metric designHard

Problem. You're testing a change to the booking funnel. The outcome you truly care about — a completed, well-rated, re-bookable stay — is rare per user and happens weeks after the experiment. How do you pick a metric you can actually decide on?

Before you reveal: say your answer out loud, as if you were in the real interview — get your reasoning across clearly first. There is no single correct answer: reading what the interviewer is really after and defending your own thinking is what makes an answer strong.
