Get more Facebook Reels viewers to react, comment and share

In a product manager interview, you are asked how you would increase interaction on Facebook Reels, the short vertical videos that people watch and post on Facebook. Walk through how you would approach the problem, what you would build, and how you would know it worked. ```hint Pin down what counts and for whom Decide which actions count as interaction, such as reacting, commenting, sharing or following, and which viewers you are trying to move. Someone who scrolls silently and someone who already reacts need different fixes. ``` ### Clarifying Questions - Which actions count as interaction: reactions, comments, shares, follows and remixes, or also watch time and completed views? - Should I focus on people watching Reels or on creators, and is there a priority market or platform, such as mobile users in a particular country? - Is the business goal behind more interaction more time spent, more creators posting, or more ad revenue, and is showing fewer ads an acceptable trade-off? ### What a Strong Answer Covers - A precise definition of interaction and why it matters to Meta, kept separate from passive watching - A chosen user segment, with a reason it has the most headroom - Pain points traced along the viewer journey, from finding Reels to reacting, commenting and sharing - Solutions prioritized by impact and effort that address the chosen segment's pain points - A success metric with guardrails against engagement bait, notification fatigue and lost ad revenue ### Follow-up Questions - Your change raises comments per viewer, but time spent on Reels falls slightly. Do you ship it? - How would you keep a push for more interaction from rewarding creators who post engagement bait? - How would you count and encourage Reels sent privately to friends in messages, where the interaction does not appear on the reel itself?
