Summary

Got a product strategy question at Google that was deceptively open-ended. The kind where you think you know where to start and then realize five minutes in you've been talking in circles.

Suggested Approach

Start by clarifying the goal and defining the metric (total watch time) and its components. Then, structure your answer by breaking down watch time into levers (e.g., users, sessions, session length) and prioritize opportunities based on impact and feasibility. Finally, propose a test-and-learn approach to validate hypotheses and iterate.

Pro tip: Anchor your answer in YouTube's business model: watch time drives ad revenue and subscription value. Show you understand the trade-offs between short-term growth hacks and long-term ecosystem health (e.g., creator incentives, user experience).

1. Clarify and Define

Ask clarifying questions to ensure alignment: Is the goal global or specific markets? What's the timeframe? Are there constraints (e.g., not sacrificing user trust)? Define total watch time as a function of DAU, sessions per user, and average session duration.

2. Break Down the Metric

Decompose watch time into its drivers: number of users, frequency of use, and time spent per session. Identify which levers have the most potential for growth based on current data and trends.

3. Generate Hypotheses

Brainstorm ideas to impact each lever. For example: increase user acquisition (e.g., partnerships, marketing), boost engagement (e.g., personalized recommendations, notifications), or extend session length (e.g., autoplay, better content discovery).

4. Prioritize and Validate

Use a framework like RICE (Reach, Impact, Confidence, Effort) to prioritize initiatives. Consider potential risks and trade-offs (e.g., user satisfaction, creator ecosystem). Propose A/B tests to measure impact.

5. Measure and Iterate

Define success metrics and guardrail metrics (e.g., user retention, satisfaction). Outline a rollout plan: start with small experiments, analyze results, and scale what works. Emphasize continuous learning.

Key Points to Mention

  • Decomposition of watch time into DAU, sessions per user, and average session duration.
  • Leveraging YouTube's recommendation algorithm to increase session length and frequency.
  • Balancing growth with user experience and creator ecosystem health.
  • Using data and experimentation (A/B testing) to validate hypotheses.
  • Considering both short-term wins and long-term strategic initiatives.
  • Acknowledging potential trade-offs, such as ad load vs. user retention.
