Facebook product critique: explain why a feature works and propose an improvement

Name a Facebook feature that you personally like and explain why it works. Then describe how you would make that feature better. ### Clarifying Questions - Is the scope the Facebook app only, or may the feature come from Messenger or other Meta apps? - Should the improvement serve the feature's users first or Facebook's engagement and revenue goals, and how should I weigh them when they conflict? - May the improvement add a new surface built on the feature, or should it change only the existing feature? ### Part 1 — Choose a feature and explain why it works State which feature you picked, who uses it and for what, and why it succeeds both for those users and for Facebook. ```hint Two kinds of value Separate what the feature does for the person using it from what it does for Facebook, and tie each to a specific design choice. ``` #### What This Part Should Cover - A specific feature, defined precisely enough to analyze - The users it serves and the need it meets for them - Why it works, linked to concrete design choices and to Facebook's goals ### Part 2 — Improve the feature Set a goal for the improvement, choose which users of the feature to focus on, find their biggest problem, propose and prioritize solutions, and explain how you would measure success. ```hint Follow one session Walk through a single visit by the user you chose and mark the moment they leave without getting what they came for. ``` #### What This Part Should Cover - A goal for the improvement and a user segment chosen with reasoning - Pain points ranked by severity for that segment - Several solutions compared on explicit criteria, with one prioritized - Success metrics with guardrails ### What a Strong Answer Covers - An improvement that builds on the strengths named in Part 1 rather than jumping to an unrelated problem - The tension between user value and Facebook's engagement or revenue goals, made explicit - Risks such as privacy, integrity or misuse, with mitigations - A clear structure and a firm recommendation ### Follow-up Questions - How would you test your improvement before a full rollout, and what result would make you stop? - If your change made the feature more useful but reduced time spent on Facebook, how would you make the case for shipping it? - How could bad actors misuse your improvement, and how would you prevent it?
