Children's Voice Assistant: Segment Choice, Safety Design and MVP Scope
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are asked to design a voice assistant product made specifically for children. Explain which children you would build it for and which needs it should meet, how the product would work, and what you would ship first.
```hint Children are not small adults
Think about how a young child's speech, reading ability, attention span and curiosity differ from an adult's, and about who else has to trust the product before a child is allowed to talk to it.

### Clarifying Questions
- Is this a standalone device, a phone or tablet app, or a children's mode inside an assistant the company already runs?
- What age range should it serve? A four-year-old who cannot read and a ten-year-old doing homework need very different products.
- Is the main purpose entertainment and companionship, learning, or everyday help such as routines and reminders?
- Which country are we launching in, given that child-privacy rules differ by market and limit what we may record?
### What a Strong Answer Covers
- A clear age band and child segment, with the parent treated as buyer and gatekeeper alongside the child as user.
- Needs specific to children: imperfect pronunciation and grammar, no reliance on reading, short attention spans, and chains of follow-up questions.
- Safety and privacy built in: age-appropriate content, parental controls, minimal data collection and compliance with child-privacy law.
- A prioritized first version and a reason it beats an adult assistant with a filter added.
- Metrics that balance a child's engagement with parent trust and healthy amounts of use.
### Follow-up Questions
- A child asks something sensitive, such as whether a pet that died will come back. How should the assistant respond?
- Parents complain that their child talks to the assistant for hours. What would you change, and what would you measure?
- How would you decide that the assistant understands young children well enough to launch?
Overview: A product design prompt asking a PM candidate to design a voice assistant made for children. It tests age-band and segment choice, child-specific needs such as imperfect speech and non-reading users, parental controls and privacy, MVP prioritization, and metrics that balance engagement with healthy use.
