What this question tests

Whether the candidate can define success for a video-first social feature launched into a mature, competitive video calling space.

Clarify the goal: Rooms aims to give casual, drop-in group video hangouts distinct from scheduled meetings like Zoom.
Define adoption metrics: rooms created per week and percent of Facebook groups or events that use a room.
Define engagement quality: average participants per room and average session duration, since casual hangouts should show sustained, not one-off, use.
Add a retention metric: percent of room creators who create a second room within 30 days.
Set a guardrail: call quality (drop rate, latency complaints), since technical reliability directly affects adoption for a video product.

Distinguishes Rooms' casual, drop-in positioning from Zoom's scheduled-meeting use case, which changes what a good session length looks like.
Uses repeat room creation, not just first use, as the real adoption signal.
Includes call quality as a guardrail, since a video product's success depends on reliability as much as feature appeal.

How would you segment success metrics for friend groups versus larger community rooms?
What would tell you this feature should be sunset?
