Summary

Meta PM interview, got a product metrics question about Instagram Stories. Pretty standard for this type of role but it made me realize how much thought goes into picking the right north star.

Author's notes

I went with daily active users who post or view at least one Story, framing it around habitual engagement rather than raw view counts.

Suggested Approach

Start by clarifying the product's core value proposition and the company's strategic goals, then propose a North Star metric that captures sustainable user engagement and aligns with long-term business success. Explain why your chosen metric is superior to alternatives, and how it balances growth with user well-being.

Pro tip: Acknowledge that the North Star metric may evolve as the product matures, and suggest a 'constellation' of supporting metrics to ensure a holistic view of health. This shows strategic thinking and avoids over-simplification.

1. Clarify Product Vision and Goals

Restate Instagram Stories' mission to connect users through ephemeral, authentic sharing, and align with Meta's broader objectives like engagement and monetization.

2. Identify the Core Value Exchange

Determine the key action that delivers value to both users and the business, such as daily active creators sharing stories that drive viewer engagement.

3. Propose a North Star Metric

Select a metric like 'Daily Active Story Creators' or 'Stories Engagement Rate' that reflects sustainable growth and user habit formation.

4. Justify and Validate the Metric

Explain why this metric predicts long-term success, how it correlates with revenue, and how it avoids vanity or easily manipulated numbers.

5. Outline Supporting Metrics and Trade-offs

Mention complementary metrics (e.g., retention, time spent, ad revenue) and discuss potential trade-offs, such as growth vs. quality.

Key Points to Mention

  • Alignment with Meta's strategic priorities, such as increasing user engagement and ad revenue.
  • The importance of a metric that reflects user habit and retention, not just raw growth.
  • Consideration of both creator and viewer sides of the marketplace.
  • Avoiding vanity metrics like total story views without context.
  • How the metric can be actionably influenced by product changes.
  • The need for a balanced set of metrics to prevent unintended consequences.
