Summary

Meta data science interview with a classic product growth question. Pretty short on details but the core ask was about DAU improvement for Facebook, which is the kind of open-ended thing that can go a dozen directions.

Author's notes

I went straight to retention and re-engagement because acquisition felt too obvious, but looking back I probably should have structured it more before diving in.

Suggested Approach

Start by clarifying the metric definition and segmenting DAU into new, resurrected, and retained users. Then propose strategies for each segment, prioritizing based on impact and feasibility, and tie them to Facebook's core value propositions.

Pro tip: Show product sense by considering trade-offs between engagement and user well-being, and reference Meta's existing products like Reels or Groups to demonstrate company knowledge.

1. Clarify the metric

Define DAU precisely: a user who logs in and performs a meaningful action. Break it down into new, resurrected, and retained users to structure your analysis.

2. Segment and prioritize

Identify which segment has the highest potential impact (e.g., resurrected users may be easier to win back than acquiring new ones). Consider Facebook's scale and maturity.

3. Generate strategies

For each priority segment, brainstorm features or initiatives. For new users: simplify onboarding; for resurrected: personalized notifications; for retained: enhance core experiences like Groups or Reels.

4. Evaluate and prioritize

Assess each strategy on impact (potential DAU lift), effort (engineering complexity), and alignment with company goals. Use a 2x2 matrix to prioritize.

5. Define success metrics

Propose metrics to measure success, such as DAU/MAU ratio, retention rate, or frequency of sessions. Suggest A/B testing to validate.

Key Points to Mention

  • DAU/MAU ratio as a measure of stickiness
  • Facebook's core value propositions: connecting with friends and family, discovering content
  • Leveraging existing products like Reels, Groups, and Marketplace to drive engagement
  • Personalization and notifications to re-engage dormant users
  • Reducing friction in onboarding for new users
  • Trade-offs between engagement and user well-being
