Leverage Data Sources for Effective Push Notification Strategy

Company: Meta

Role: Data Scientist

Category: Analytics & Experimentation

Difficulty: medium

Interview Round: Technical Screen

##### Scenario A product team wants to improve the quality of push notifications sent to users. ##### Question What data sources would you leverage to design and deliver high-quality push notifications? Which key metrics would you monitor to judge the success of the push notification strategy? Describe how you would measure and quantify any negative impact caused by sending notifications. ##### Hints Consider user behavioral logs, segmentation attributes, A/B test design, engagement and retention metrics, opt-out rates, and ways to compare test vs. control groups.

Data Sources and Metrics for Push Notification Strategy

A product team wants to improve the quality and impact of mobile push notifications for a consumer app. Assume you have access to event logging, notification-delivery logs, user attributes, and an experimentation platform.

Constraints & Assumptions

  • Optimize for incremental user value, not just raw opens.
  • Include both targeting/design data and measurement data.
  • Discuss negative impact such as opt-outs, churn, annoyance, cannibalization, and notification fatigue.
  • Propose an experiment or holdout strategy to measure causality.

Clarifying Questions to Ask Guidance

  • What is the product goal: retention, reactivation, conversion, content discovery, or revenue?
  • Are notifications transactional, recommendation-based, promotional, or lifecycle messages?
  • What user controls exist for notification categories, quiet hours, and frequency caps?
  • Is there a long-term holdout group?

What a Strong Answer Covers Guidance

  • Data sources: behavioral logs, notification pipeline logs, user profile and device data, preferences, historical engagement, content inventory, experiments, and downstream outcomes.
  • Feature and segmentation ideas: recency/frequency, affinity, lifecycle stage, timezone, device, language, churn risk, purchase propensity, and prior notification response.
  • Success metrics: incremental opens, downstream conversions, sessions, retention, revenue, content engagement, and long-term user value.
  • Guardrails: opt-out rate, uninstalls, spam complaints, app crashes, latency, negative feedback, muted categories, and engagement cannibalization.
  • Causal measurement: randomized holdouts, frequency experiments, intent-to-treat analysis, CUPED or covariate adjustment, and long-term fatigue tracking.
  • Quantifying harm by comparing treatment and control on opt-outs, churn, session quality, and downstream value.

Follow-up Questions Guidance

  • How would you set a frequency cap?
  • How would you choose send time for each user?
  • What metric would stop a rollout even if open rate increased?
  • How would you distinguish incremental engagement from cannibalized organic engagement?
