What this question tests
Ability to set stage-appropriate goals and articulate real trade-offs between competing metrics.
How to approach it
- State the strategic goal for Reels: compete for short-form video attention and time spent against TikTok, while building a sustainable creator ecosystem.
- Define a primary metric: time spent on Reels and daily reach (percent of users watching at least one Reel), reflecting attention capture.
- Define a creator-health metric: number of active creators posting Reels and their monetization (bonuses, ads revenue share).
- Identify the core trade-off: maximizing viewer time spent can favor addictive, low-effort content, while creator monetization needs sustained, quality content investment.
- Recommend balancing both with a guardrail: content diversity or creator retention rate, so short-term watch time doesn't erode long-term supply.
- Define success as growth in both time spent and creator retention together, not either alone.
What a strong answer includes
- Names the real trade-off explicitly: viewer engagement metrics can conflict with sustainable creator incentives, a genuine tension in short-form video.
- Gives an illustrative target, e.g. growing average daily Reels time from 15 to 25 minutes per active user, marked as an assumption.
- Proposes creator retention as a counterbalancing guardrail, showing two-sided marketplace thinking.
- Explains why competing purely on watch time against TikTok is a losing long-term strategy without creator supply health.
Common mistakes
- Naming only viewer-side metrics and ignoring the creator side of the marketplace.
- Not naming any explicit trade-off, despite the question directly asking for one.
Likely follow-up questions
- How would you balance watch time growth against content quality?
- What would you do if creator retention dropped while watch time grew?
