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.
Strong-answer signal: stating a hypothesis before segmenting, then attributing the points (7 + 3 + 2 = 12) instead of stopping at the first plausible cause; separating self-inflicted/fixable from market causes. Common trap: jumping to "demand is down" and proposing a promo, when the real issue is a payment regression a promo would only mask. Trains: hypothesis-before-segment; funnel-attribution.
