Strategy question

You are the PM at Facebook Post. What reactions should we add next?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Product thinking on expanding a lightweight interaction feature without diluting its simplicity or signal value.

Clarify the goal: are new reactions meant to increase expression richness, engagement, or better sentiment signal for ranking.
Assess current gaps: existing reactions like Like, Love, Haha, Wow, Sad, Angry may miss nuanced sentiments like support or curiosity.
Prioritize by evidence: look at comment text analysis for sentiments not captured by existing reactions, like empathy for difficult posts.
Propose a specific addition, for example a Support or Care-style reaction for posts about hardship, filling a real emotional gap.
Weigh the tradeoff: too many reaction options increases decision friction and dilutes the simplicity that makes reactions fast to use.
Success metric: adoption rate of the new reaction, and whether it reduces low-signal comment volume on relevant post types.

Identifies a real, specific gap, like the lack of empathetic non-celebratory reactions, grounded in Facebook's actual known reaction set (common knowledge).
Weighs the tradeoff explicitly: more reactions add expressiveness but risk diluting the one-tap simplicity that makes reactions valuable.
Ties the new reaction to a measurable signal improvement, not just novelty.
