Summary

Interviewed at Google for a product role and got hit with a classic prioritization question about mobile feed real estate. Not a lot of context to go on, but the question itself was meaty enough to chew on for a while.

This is the kind of question where you can spiral fast if you don't anchor on what you're actually optimizing for.

Suggested Approach

Start by clarifying the goal: maximize long-term user value and revenue, not just short-term engagement. Then propose a framework that balances user experience, advertiser value, and platform health, using data and experimentation to determine the optimal mix. Finally, outline how you would measure success and iterate.

Pro tip: Acknowledge the trade-off between short-term revenue and long-term user retention, and emphasize that the right split depends on user segments and context. Show you would use holdout experiments to measure the causal impact of ads on engagement.

1. Clarify Objectives and Constraints

Define the primary goal (e.g., maximize long-term revenue while maintaining user engagement) and constraints (e.g., user satisfaction, advertiser demand, content diversity).

2. Identify Key Metrics

Select metrics that capture both user and business value: daily active users, time spent, ad revenue, user satisfaction, and ad quality metrics like click-through rate and relevance.

3. Segment Users and Contexts

Recognize that the optimal split varies by user demographics, usage patterns, and time of day. Consider new vs. existing users, and high vs. low engagement users.

4. Design Experiments

Run controlled experiments (A/B tests) with different ad-to-suggestion ratios to measure causal impact on key metrics. Use holdout groups to assess long-term effects.

5. Optimize and Iterate

Use experiment results to build a model that dynamically allocates space based on predicted user response and advertiser value. Continuously monitor and adjust.

Key Points to Mention

  • Trade-off between short-term ad revenue and long-term user engagement/retention
  • Importance of user experience and ad relevance to avoid ad fatigue
  • Use of experimentation (A/B testing) to determine optimal mix
  • Segmentation by user type and context (e.g., new users, high-value users)
  • Dynamic allocation based on real-time signals and predicted outcomes
  • Alignment with Facebook's mission and business model
