What this question tests
Metrics fundamentals for a content business: can you name a coherent metric tree covering acquisition, engagement, retention and monetization for streaming.
How to approach it
- Acquisition: new subscriber signups and trial-to-paid conversion rate.
- Engagement: hours watched per user per week and content completion rate (finishing episodes/seasons).
- Retention: monthly/annual churn rate, and cohort retention curves by signup month.
- Monetization: ARPU, and for ad-supported tiers, ad load and RPM.
- Content-specific: title-level performance (watch share, completion) to guide content investment decisions.
- Tie it together: explain how these metrics feed content and pricing decisions, not just report health.
What a strong answer includes
- Organizes metrics into a clear tree (acquisition, engagement, retention, monetization) instead of a flat list.
- Names churn/retention as central to a subscription business, since streaming's real risk is high churn, not low signups.
- Includes content-level metrics (title performance), which is specific to a streaming business versus generic apps.
- Explains how metrics inform decisions, e.g. low completion rate flags content or pacing issues.
Common mistakes
- Listing generic app metrics (DAU, session length) without anything specific to a subscription content business.
- Omitting churn, which is the single most important health metric for this category.
Likely follow-up questions
- Which one metric would you watch most closely week to week, and why?
- How would you use title-level metrics to guide content investment?
