Strategy to Multiply a Consumer App's Engagement a Hundredfold

You are interviewing for a product manager role at Google. Pick any mobile app you know well, and lay out how you would make its user engagement grow 100 times. ```hint Size the gap before the ideas A hundredfold change will not come from polishing existing screens. Think about which parts of engagement could realistically grow by an order of magnitude for the app you choose, and pick the app with that in mind. ``` ### Clarifying Questions - How should engagement be measured: daily active users, sessions per user, time spent, or how often users perform the app's core action? - Is 100x a literal target with a deadline, or a way to push for step changes instead of incremental tweaks? - Is any app fair game, or would you prefer that I choose a Google product? - Should the growth come from existing users engaging more, from new users, or from both? ### What a Strong Answer Covers - A deliberate app choice and a precise definition of engagement, with the reasoning behind both - A breakdown of engagement into levers and a sized, plausible path toward 100x - Step-change ideas rooted in specific user pain points, prioritized by impact and effort - A north-star metric with guardrails against unhealthy engagement, such as notification spam or time spent with no value - Candor about whether 100x is achievable and over what time frame ### Follow-up Questions - Your first launch doubles sessions, but 30-day retention does not move. What do you conclude, and what do you do next? - How would your plan change if the app you picked already had billions of daily users? - Which idea would you test first, and how would you design the experiment if the feature is social?
