What this question tests
Metrics design for a new feature format: can you define goals and a metric tree for a voice only live feature distinct from video live streaming.
How to approach it
- State the goal: give users a lower effort way to broadcast live than video, growing live participation overall.
- Set the north star as weekly active broadcasters using voice live, since low broadcaster supply is usually the bottleneck for any live feature.
- Add listener side metrics: concurrent listeners per session and average listen duration.
- Add guardrails: audio quality or drop rate, and abuse reports, since voice only removes visual moderation cues.
- Compare against the video live baseline to see if voice attracts broadcasters who found video too high effort.
- State you would confirm whether this targets casual creators or existing established broadcasters.
What a strong answer includes
- Prioritizes broadcaster supply as the north star, since a live feature is worthless without people going live.
- Flags moderation as a real guardrail, since audio only removes visual cues that catch abuse in video.
- Compares against the existing video live product to isolate what voice actually adds.
Common mistakes
- Copying video live metrics wholesale without adjusting for the lower barrier voice offers.
- Ignoring moderation risk specific to audio only content.
Likely follow-up questions
- Would you expect voice live to cannibalize video live usage, and how would you check?
- How would you detect abuse in an audio only format?
