Company: Meta
Role: Product Manager
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Other
You are the product manager for Instagram Reels, Instagram's short-form video feature, which has just been released in 150 countries. Set the goals for Reels and define the metrics you would use to decide whether it is succeeding.
```hint Start from why Reels exists
Work out what Reels should do for viewers, for creators and for Instagram as a whole before naming any metric. Then ask how the answer should differ between the first weeks after launch and later, and across very different markets.
```
### Clarifying Questions
- How long ago was the release? Should the goals cover the first weeks of adoption, the coming year, or both?
- What does leadership most want from Reels: more time spent on Instagram, a reason for creators to post short videos on Instagram, or reaching new users?
- Should success be judged for Reels alone, or by its net effect on Instagram, including Feed and Stories?
- Are all 150 countries weighted equally, or do some markets matter more, such as those where competing short-video apps are dominant or unavailable?
### What a Strong Answer Covers
- Goals for each group Reels serves (viewers, creators and Instagram overall), linked to why the product was built
- A precisely defined north-star metric with its unit and time window, and why it beats the alternatives
- Supporting metrics for consumption and creation, plus guardrails for cannibalization of Feed and Stories, content quality and integrity
- How the scorecard differs between the launch period and steady state, and how results are compared across 150 countries
- How to separate real impact from novelty and from Instagram's underlying growth, for example with holdouts and cohort analysis
### Follow-up Questions
- Time spent on Reels rises sharply while time on Feed and Stories falls by a similar amount. Is the launch a success?
- Most first-time creators never post a second reel. Which metric reveals this, and what would you do about it?
- How would you compare results between countries with very different network speeds and phone types?
