Upgrading Facebook Groups: goal, target segment, prioritized fixes and success metrics

You are a product manager on Facebook Groups, a mature product that people use to gather around shared interests, places and needs. Tell the interviewer how you would make Groups better, then explain how you would know whether your change worked. Settle the goal and the people you are designing for before proposing anything. ```hint Look at both sides of a group A group stays alive only if someone runs it and other people keep coming back. Trace one week in a single group from the admin's view and from a member's view, and note the moment each one is most likely to disengage. ``` ### Clarifying Questions - Is the improvement meant to deepen participation inside groups, help people discover groups worth joining, or give groups a way to earn money? - Which kinds of groups are in scope: interest communities, local buy-and-sell groups, support groups, or groups run by brands and businesses? - Is the answer about the mobile app, the web, or both? - Can a change add work for admins, or should anything they have to do be close to effortless? ### What a Strong Answer Covers - An objective for the improvement that suits a mature product and Meta's aim of building community, with the reason it was chosen - The people who run groups and the people who join them segmented, with one segment chosen and justified against the objective - That segment's pain points, drawn from how they actually use a group and ranked by severity - Solutions weighed on impact, effort and the side effects each could create inside a group, ending in a clear priority - A primary success metric with guardrails, and an experiment design that holds up when members of the same group affect one another ### Follow-up Questions - If your primary metric rose but reports of spam or harassment in groups rose too, what would you do? - How would your plan differ for a small neighborhood group versus a group with hundreds of thousands of members? - How would you tell whether the change created new participation or only moved activity from the main feed into groups?
