Summary

PM interview at Meta, one question about push notification metrics. Not much else to go on but it's the kind of question that sounds easy and then you realize mid-answer you've been too shallow.

I went straight to open rate and click-through and felt pretty good about it, then realized I'd skipped the whole retention and opt-out side of things.

Suggested Approach

Start by clarifying the goal of push notifications (e.g., re-engagement, conversion, retention) and the product context. Then, structure your answer around a metrics framework like HEART or AARRR, covering reach, engagement, and downstream impact. Finally, emphasize balancing short-term metrics with long-term user value and avoiding notification fatigue.

Pro tip: Show maturity by discussing guardrail metrics (e.g., opt-out rate, notification disablement) and the trade-off between short-term engagement and long-term user trust. Mention that success depends on the notification's purpose and user segment.

1. Clarify Objective and Context

Ask clarifying questions to understand the notification's goal (e.g., re-engagement, promotion, transactional) and the target user segment. This ensures you measure what matters for that specific use case.

2. Define Success Metrics Across Funnel

Identify KPIs for each stage: delivery (sent, delivered), engagement (open rate, click-through rate), and conversion (action completion, revenue). Also consider retention and long-term value metrics.

3. Include Guardrail Metrics

Propose metrics to monitor negative side effects, such as opt-out rate, notification disablement, app uninstalls, and user sentiment. These ensure you're not sacrificing long-term health for short-term gains.

4. Prioritize and Set Targets

Select the most relevant KPIs based on the objective and set benchmarks or targets. Explain how you would prioritize them (e.g., primary vs. secondary) and why.

5. Iterate and Optimize

Describe how you would use these KPIs to run A/B tests, segment users, and continuously improve notification strategy. Highlight the importance of monitoring trends over time.

Key Points to Mention

  • Open rate and click-through rate (CTR) as core engagement metrics
  • Conversion rate and downstream actions (e.g., purchase, content view)
  • Retention and re-engagement impact (e.g., DAU/MAU lift)
  • Opt-out rate and notification disablement as guardrails
  • Segmentation by user cohort, notification type, and frequency
  • Balancing short-term engagement with long-term user experience
