Begin with the goal: "I start by asking what problem the feature solves, then define metrics that ladder up to that outcome." Structure your answer: 1) North Star metric (e.g., retention), 2) leading indicators (e.g., adoption rate), 3) guardrails (e.g., support tickets). Common mistake: listing vanity metrics like DAU without explaining why they matter. Stronger framing: "Metrics aren’t just numbers; they’re a story about whether the feature is working."
