Set goals and success metrics for Facebook's onboarding of brand-new users
Company: Meta
Role: Product Manager
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Other
You are a product manager at Meta responsible for Facebook's new user experience: what people encounter when they first join. What goals would you set for it? Explain what the experience should achieve, how you would turn that into measurable goals, and which metrics and guardrails you would track.
```hint Find the early sign of a lasting user
A newcomer's first days largely decide whether they come back. Work out what someone must experience early on to keep getting value from Facebook, and express the goal in those terms rather than in raw time spent.

### Clarifying Questions
- Does "new user" mean only people creating their first Facebook account, or also people returning after a long absence or arriving from another Meta app?
- Does the experience cover only the sign-up and onboarding screens, or the first few weeks of use?
- Which markets and devices matter most, for example places where Facebook still has room to grow and many people use low-end phones with limited data?
- Is the goal purely growth and retention, or should the experience also aim for safety and fewer fake accounts?
### What a Strong Answer Covers
- Goals derived from Facebook's mission and from what keeps people coming back (real connections, relevant content, the reason they joined), not a list of available actions.
- A concrete, data-validated definition of activation within a time window, and a primary goal metric tied to longer-term retention.
- A funnel and supporting metrics across sign-up, profile, first connections and first meaningful interactions, segmented by market, device and reason for joining.
- Guardrails against harmful optimization such as spammy friend suggestions, notification overload, fake accounts and time spent that comes from confusion.
### Follow-up Questions
- A change that adds more friend suggestions raises activation, but day-30 retention does not move. How do you interpret that, and what would you do next?
- How should the goals change for a new user in a country where most of their friends are not on Facebook yet?
- How would you keep fake and spam accounts from distorting these goals?
Overview: Meta product manager interview question on setting goals for the experience Facebook gives people who have just joined. It tests defining activation, tying onboarding goals to long-term retention, choosing a primary metric with a funnel and segments, and adding guardrails against spammy growth tactics and fake accounts.
