Product Sense: Build a Facebook Product for Kids, From Target Age to Safety Metrics
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager at Facebook and have been asked to design a new service for children. Decide who it should serve and what it should do, take the design from the user problem to a first version, and explain how you would know it is succeeding.
```hint A children's product has more than one user
Children rarely choose or control the apps they use, and a product for them operates under rules that adult Facebook products do not. Decide early whose problem you are solving and what the service must never do.

### Clarifying Questions
- Which ages count as children here: kids below Facebook's minimum account age of 13, teenagers, or both?
- What is the goal for Meta: bringing families closer, building a future audience, or a new business line? May the service carry ads or charge a fee?
- Should this be a standalone app for the child, a feature parents use inside Facebook, or both?
- Which countries are in scope, given that rules on children's data differ by market?
### What a Strong Answer Covers
- A goal tied to Meta's mission and a clear reason a children's service is worth the risk.
- Segmentation by age and by the adults around a child (parents, relatives, educators), with a justified target.
- Specific pain points and solutions, prioritized into a defined first version.
- Success metrics that reward healthy connection rather than time spent, with safety and trust guardrails.
- Child safety, privacy, regulatory and reputational risks, each with a concrete mitigation.
### Follow-up Questions
- Parent groups publicly object to the launch. How do you respond, and what would you change?
- What should happen when a child using the service turns 13?
- Leadership asks how this service makes money. What is your answer?
