What this question tests
Tests translating a known strategic pivot, Meaningful Social Interactions, into concrete signals and levers a new PM could act on.
How to approach it
- Recall the goal: shift ranking from passive public content toward interactions between people who know each other.
- List signal categories: comment depth and reciprocity between friends, message-triggered shares, and group participation versus passive scrolling.
- Propose one lever: rank content higher when it comes from a close-friend group with reciprocal engagement history, and demote low-interaction public posts.
- Add guardrails: watch time and creator page traffic, since deprioritizing public content has real downside for publishers.
- Define success as time spent in meaningful interactions, like commenting or messaging, not total time spent.
What a strong answer includes
- Names concrete signals, reciprocal comments, close-friend group activity, instead of a vague more-interaction answer.
- Explicitly flags the real tradeoff Meta faced, publisher and Pages traffic dropping as a side effect.
- Picks a quality-weighted time metric over raw engagement volume.
Common mistakes
- Optimizing for total engagement without distinguishing meaningful from passive interactions.
- Ignoring the real downside this shift caused for publishers and Pages.
Likely follow-up questions
- How would you measure whether an interaction is genuinely meaningful versus just more comments?
- How would you handle publisher backlash from reduced reach?

- Imagine you are the PM in charge of Reactions on Facebook - the new way to interact with posts by using “love”, “haha”, “wow”, “sad”, and “angry” reactions. What would success look like in terms of number of non-like reactions per post at launch and how do you come up with this? Would this number differ by reaction? Why or why not?Meta · Metrics · Hard
