Went straight to open rate and kind of stopped there for a beat too long.
Start by clarifying the goal of push notifications—likely to drive user engagement and retention without being intrusive. Then propose a framework that balances user experience, business impact, and long-term health, using metrics like CTR, opt-out rate, and downstream conversions. Emphasize the need for A/B testing to establish causality and guardrail metrics to prevent harm.
Pro tip: Always pair engagement metrics with guardrails like notification disable rate and user satisfaction to show you understand the trade-offs between short-term gains and long-term user trust. Mention that at Meta, the scale and diversity of users mean you must segment metrics by user cohorts and notification types.
Ask clarifying questions to understand the primary goal (e.g., re-engagement, feature adoption) and any constraints (e.g., frequency caps, user control). This ensures your metrics align with business and user needs.
Identify key performance indicators (KPIs) that directly measure the desired outcome, such as click-through rate (CTR), conversion rate, or retention lift. These are your primary metrics.
Select metrics to monitor negative side effects, such as opt-out rate, notification disable rate, app uninstalls, or user reports. These ensure you're not sacrificing long-term user experience for short-term gains.
Look beyond immediate actions to metrics like 7-day or 30-day active usage, session quality, or overall engagement. Also consider how notifications affect other channels (e.g., email, in-app).
Propose an experimentation plan to measure the causal impact of notifications, including holdout groups and statistical significance. This ties metrics to actionable insights.

Start by clarifying the problem: define what 'too many' means, identify affected user segments, and quantify the impact. Then propose a data-driven framework to diagnose root causes, prioritize solutions, and measure success. Emphasize balancing user experience with business goals like engagement and retention.
Pro tip: Frame the problem as an optimization between notification volume and user value, and suggest running controlled experiments to find the optimal frequency. Show awareness of Meta's focus on meaningful interactions and long-term user satisfaction.
Ask clarifying questions to understand the complaint: which notifications, which user segments, and what metrics define 'too many'. Define success metrics such as notification opt-out rate, CTR, and user satisfaction.
Analyze notification logs to identify patterns: frequency, timing, relevance, and user engagement. Segment users by demographics, behavior, and notification preferences to pinpoint over-notification.
Brainstorm potential fixes: frequency capping, smarter targeting, user controls, or content personalization. Prioritize based on impact, effort, and alignment with business goals.
Propose A/B tests to measure the effect of changes on key metrics. Use holdout groups to assess long-term impact on retention and engagement.
After validating improvements, roll out to all users and set up ongoing monitoring to prevent recurrence. Establish a feedback loop for continuous optimization.

Frame the problem as a constrained optimization: maximize open rates subject to a guardrail on uninstalls. Propose a data-driven solution that estimates per-user treatment effects (e.g., using uplift modeling or bandits) and dynamically allocates a daily notification budget. Emphasize experimentation and monitoring to validate the approach.
Pro tip: Highlight the importance of defining a clear guardrail metric (e.g., uninstall rate) and using a holdout group to measure long-term effects, showing you understand the trade-off between short-term engagement and user retention.
Clarify the goal: maximize open rates while keeping uninstalls below a threshold. Identify key metrics: open rate, uninstall rate, and possibly notification fatigue indicators.
Use historical data to estimate each user's likelihood to open a notification and their sensitivity to notification frequency. Consider uplift modeling to predict the incremental effect of sending an additional notification.
Formulate as a constrained optimization problem: allocate up to N notifications per user per day to maximize expected opens, subject to uninstall risk. Use techniques like linear programming, bandits, or reinforcement learning to solve dynamically.
Run A/B tests to compare the algorithm against a baseline (e.g., fixed cap) and measure both open rates and uninstalls. Use holdout groups to assess long-term impact.
Deploy with real-time monitoring of guardrail metrics. Continuously update models with new data and adjust the cap as user behavior evolves.
