Question“Tell me about a time you disagreed with engineering leadership.”
Weak answer
We were building a new feature and I thought the timeline was wrong. I talked to my manager about it and we ended up adjusting some things. It worked out fine in the end and we shipped the feature.
Strong answer
Situation: our team had committed to shipping checkout v2 in six weeks. Task: as PM I owned the scope, and I believed the timeline would force us to cut fraud checks. Action: I pulled the last two incident reports, modelled the chargeback risk at about 40,000 euros a month, and proposed a two-week extension with a phased rollout instead. I walked the eng director through the numbers one-on-one before raising it in the planning review. Result: we shipped two weeks later with fraud checks intact, chargebacks stayed flat, and that risk-modelling step became part of our standard scoping.
Why the strong version wins: The strong answer owns a specific decision ("I"), puts a number on the stakes, shows three concrete actions with a trade-off, and ends with a quantified result plus what changed afterwards. The weak answer is all "we", has no metric, and never says what the disagreement actually was.
