Summary

Meta product sense interview, one question about Facebook Dating and whether you'd ship an algorithm change. Pretty focused session, no fluff.

Questions Asked (1)

Q1

The engineering team has built an algorithm update that's projected to increase Facebook Dating matches by 10%. Would you launch it?

My first instinct was to just say yes, 10% lift sounds good, ship it.

Suggested Approach

Start by clarifying the goal and constraints, then evaluate the algorithm update against key metrics beyond matches, such as user engagement, retention, and monetization. Propose a structured testing plan to validate the 10% lift and assess potential risks before making a launch decision.

Pro tip: Always consider second-order effects: an increase in matches might not translate to meaningful conversations or dates, and could even harm user experience if it leads to lower-quality matches. Emphasize the importance of measuring downstream metrics and guardrails.

1. Clarify the Objective and Constraints

Ask clarifying questions to understand the goal (e.g., increase matches vs. meaningful connections), timeline, resources, and any strategic priorities for Facebook Dating.

2. Define Success Metrics and Guardrails

Identify primary metrics (e.g., matches, conversations, dates) and guardrail metrics (e.g., user satisfaction, retention, reports) to ensure the update doesn't negatively impact the ecosystem.

3. Evaluate the Algorithm Update

Assess the credibility of the 10% projection: review the methodology, sample size, and potential biases. Consider if the lift is statistically significant and practically meaningful.

4. Design an Experiment

Propose an A/B test to validate the update in a controlled environment, measuring both primary and guardrail metrics. Determine sample size, duration, and success criteria.

5. Make a Launch Decision

Based on experiment results, decide whether to launch, iterate, or abandon. Consider a phased rollout to monitor long-term effects and gather user feedback.

Key Points to Mention

  • Distinguish between quantity and quality of matches; ensure the update leads to meaningful connections, not just more matches.
  • Consider network effects and market dynamics: an increase in matches for some users might come at the expense of others.
  • Evaluate potential unintended consequences, such as increased spam, harassment, or decreased user trust.
  • Use a holdout group to measure long-term impact on retention and engagement.
  • Align with Meta's broader goals for Facebook Dating, such as user growth, monetization, and ecosystem integration.
  • Communicate a clear recommendation with data-driven reasoning, acknowledging uncertainties and next steps.
