I jumped straight to engagement metrics and the interviewer kind of waited, like they wanted me to slow down.

Suggested Approach

Start by clarifying the goal of ads on Reels: to monetize without harming user engagement. Then define success metrics across user, advertiser, and platform dimensions, and outline a measurement plan including guardrail metrics and experiments.

Pro tip: Emphasize the importance of balancing short-term revenue with long-term user retention, and propose a phased rollout with holdout groups to measure incremental impact.

1. Clarify Objectives

Confirm the primary goal: monetization while maintaining or improving user experience. Identify key stakeholders and their success criteria.

2. Define Success Metrics

Choose metrics across three categories: user engagement (e.g., time spent, retention), advertiser value (e.g., CTR, conversion rate), and platform revenue (e.g., ad revenue per user).

3. Establish Guardrail Metrics

Identify metrics that should not degrade, such as user-reported satisfaction, churn rate, and content creation metrics.

4. Design Measurement Plan

Propose A/B tests with control groups, longitudinal studies, and cohort analysis to measure both short-term and long-term effects.

5. Iterate and Optimize

Outline how you would use data to refine ad formats, frequency, and targeting to improve both user and advertiser outcomes.

Key Points to Mention

  • North Star Metric: e.g., ad revenue per user while maintaining DAU/MAU ratio
  • Counter metrics: user engagement (watch time, likes, comments), retention, and churn
  • Advertiser metrics: click-through rate, conversion rate, return on ad spend
  • Experimentation: A/B testing, holdout groups, and incremental lift measurement
  • Long-term effects: brand perception, user trust, and ecosystem health
  • Trade-offs: short-term revenue vs. long-term user satisfaction
