How to answer navigate competing metrics for one feature in PM interview

When metrics conflict—like increased engagement reducing retention—diagnose the root tension through segmentation and time-lagged analysis. Identify which metric aligns with long-term value and which reflects short-term behavior. Propose countermeasures to mitigate tradeoffs, such as adjusting the user journey or refining targeting. Show how you communicate this tradeoff transparently to stakeholders using data-backed narratives, not gut calls.
