Company: Meta
Role: Product Manager
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Other
You are the product manager responsible for Facebook Pages, the public presences that businesses, brands, creators, public figures and organizations run on Facebook. People follow a Page to see its posts, and they can message it, comment on its posts or leave a recommendation. How would you define what success means for Pages, and which metrics would you use to measure it?
```hint Both sides of a Page
A Page is useful only when its owner and the people who visit it both get something from it. Work out what each side wants from Pages, and why Pages matter to Meta's business, before choosing a metric.
```
### Clarifying Questions
- Which Page owners matter most here: small local businesses, large brands, creators and public figures, or nonprofits and community groups?
- Is this an overall health measure for a mature product, or are we judging a specific recent change to Pages?
- Should success put value to Page owners first, value to people on Facebook, or Meta's revenue from Pages that go on to advertise?
- Do Messenger conversations with a Page and paid promotion of Page posts count as part of the Pages product for this exercise?
### What a Strong Answer Covers
- The purpose of Pages for owners, for people on Facebook and for Meta, turned into a clear goal.
- Segments of Page owners and the main steps of the owner and visitor journeys.
- One north-star metric with a reason it beats obvious alternatives such as follower counts, backed by a few input metrics across the journeys.
- Guardrails for spam, engagement bait, Page security and the Feed experience, and the limits of what the metrics can see.
### Follow-up Questions
- Total followers are rising, but the share of followers who interact with any Page post is falling. Is Pages getting healthier?
- How would you tell whether Pages drive real outcomes for small businesses when the sale happens offline, in a shop?
- Leadership suggests the team's goal should be the number of new Pages created each month. How do you respond?
- Leadership wants this turned into the Pages team's goals for next year. How would you set concrete target values for the north-star metric, the supporting metrics and the guardrails?
