Summary

Meta PM interview, product sense round focused on short-form video. Just one question but it had a lot of surface area and I don't think I covered it well enough.

I went straight to engagement metrics and kind of talked myself in circles.

Suggested Approach

Start by clarifying the goal of Facebook Reels (e.g., drive engagement, grow user base, monetize) and then define success metrics across the user journey. Use a structured framework like HEART or AARRR to cover acquisition, engagement, retention, and monetization, and tie metrics to business objectives.

Pro tip: Emphasize that success metrics should be leading indicators of long-term ecosystem health, not just short-term vanity metrics; for example, prioritize meaningful engagement (e.g., shares, comments) over raw view counts.

1. Clarify the Goal

Ask clarifying questions to understand the primary objective of Facebook Reels (e.g., increase time spent, attract creators, compete with TikTok).

2. Choose a Framework

Select a metric framework like HEART (Happiness, Engagement, Adoption, Retention, Task Success) or AARRR (Acquisition, Activation, Retention, Referral, Revenue) to structure your answer.

3. Define Metrics per Stage

For each stage, propose specific metrics: e.g., DAU/MAU for engagement, watch time per user, retention rate, number of creators, revenue per user.

4. Prioritize and Set Targets

Identify the North Star metric (e.g., daily watch time) and secondary metrics, and suggest how to set targets based on benchmarks or experiments.

5. Monitor and Iterate

Explain how you would track metrics over time, run A/B tests to validate changes, and adjust strategy based on data.

Key Points to Mention

  • North Star Metric: e.g., daily watch time or meaningful engagement rate
  • Engagement metrics: likes, comments, shares, saves, and watch-through rate
  • Retention: day 1/7/30 retention of users and creators
  • Monetization: ad revenue, in-app purchases, or creator payouts
  • Ecosystem health: creator growth, content diversity, and user-reported satisfaction
  • A/B testing: to measure causal impact of product changes on key metrics
