Tell me about a decision you made on a feature, and the option you rejected.
Answer it out loud before you open anything. The value of the flags below is in comparing them to what you actually said.
The situation behind the question
A behavioural question in a product-engineering interview. The interviewer wants a real example; a hypothetical is allowed if the candidate says so. The follow-ups probe whether the reasoning survives contact with a sceptic.
What it is really testing
Whether the candidate can name a trade-off rather than a preference. Engineers describe decisions as "we chose X because it was better". The skill is saying what X cost, what the rejected option would have given, and what evidence would have flipped the choice — which is what makes a decision explainable later.
