Summary

Meta PM interview, got hit with a classic metrics decline question. Pretty standard case format but the specifics of Facebook's social graph make it trickier than it looks.

You're a PM for Facebook. Friend requests are down 10%. What would you do?

I jumped straight into diagnosis mode, which felt right, but I think I spent too long on the metric itself before clarifying what 'down' even meant.

Suggested Approach

Start by clarifying the metric definition and segmenting the 10% drop to identify where and when it occurred. Then form hypotheses about root causes across internal and external factors, prioritize the most likely ones, and propose data-driven next steps to validate and address the issue.

Pro tip: Demonstrate a structured, hypothesis-driven approach while emphasizing the importance of understanding the 'why' behind the metric before jumping to solutions. Show that you can balance quick wins with long-term strategic thinking.

1. Clarify and Define

Ask clarifying questions to understand the metric: How is 'friend requests' defined? Is it requests sent, accepted, or both? What is the time frame and baseline? Are there any recent changes or events?

2. Segment and Localize

Break down the metric by dimensions such as user demographics, geography, platform, and time to identify which segments are driving the decline.

3. Generate Hypotheses

Brainstorm potential root causes: internal (product changes, bugs, algorithm updates) and external (seasonality, competition, privacy concerns, market trends).

4. Prioritize and Validate

Prioritize hypotheses based on impact and likelihood, then outline how to validate them using data analysis, user research, or experiments.

5. Recommend Actions

Propose immediate fixes if a clear cause is found, and suggest longer-term strategies to improve friend request metrics, such as product improvements or growth initiatives.

Key Points to Mention

  • Metric definition and segmentation (e.g., new vs. existing users, platform, geography)
  • Internal factors: recent product changes, bugs, algorithm updates, UX changes
  • External factors: seasonality, competition, privacy regulations, cultural shifts
  • Data analysis: cohort analysis, funnel analysis, A/B testing
  • User research: surveys, interviews to understand user behavior
  • Prioritization frameworks: impact vs. effort, RICE, etc.
  • Cross-functional collaboration: working with data science, engineering, design, marketing
