What this question tests
Ability to choose stage-appropriate metrics for a growing feature rather than reusing mature-product metrics.
How to approach it
- State the growth-phase goal: expanding the base of people who both broadcast and watch live video, not yet maximizing monetization.
- Define an activation metric: percent of eligible users who go live at least once, since low awareness or friction likely caps this.
- Define an engagement metric: average concurrent viewers per broadcast and viewer watch time, as a proxy for content quality.
- Define a retention metric: percent of broadcasters who go live again within 30 days.
- Set a guardrail: report or moderation rate, since growth-stage feature pushes can increase exposure to low-quality or unsafe content.
What a strong answer includes
- Separates broadcaster-side metrics (who creates) from viewer-side metrics (who watches), since growth needs both to compound.
- Gives an illustrative target, e.g. raising repeat broadcaster rate from 10% to 18% in a quarter, marked as an assumption.
- Explains why revenue metrics are premature in a growth phase and would misdirect the team's focus.
- Flags moderation guardrails as essential since live video has higher real-time risk than static content.
Common mistakes
- Jumping to monetization metrics before the feature has enough active broadcasters and viewers.
- Picking only viewer-side metrics and ignoring what drives people to start broadcasting.
Likely follow-up questions
- How would these metrics change once the feature matures?
- What would you do if broadcaster activation was high but repeat rate was low?
