Interview Round: Other
You are a product manager on WhatsApp. COVID-19 lockdowns are keeping children at home. How would you grow WhatsApp's adoption among kids during this period?
```hint Who holds the phone
Consider whose device and whose permission a child's use depends on, and what the lockdown changed about who children need to talk to.

### Clarifying Questions
- Does "kids" mean children younger than WhatsApp's minimum sign-up age, teenagers who can already have accounts, or both?
- Which markets matter most: places where WhatsApp is already the default app for families and schools, or places where it is a minority app?
- Is the goal new accounts during the lockdown, engagement, or users who stay after schools reopen?
- May the solution be a separate supervised experience, or must it live inside the main app?
### What a Strong Answer Covers
- A clear definition of the target age group and the legal and policy limits that come with it
- The lockdown-specific needs of children and of the parents, teachers and relatives around them
- Features prioritized by impact and safety risk rather than novelty
- Success metrics with safety and trust guardrails, and a view on retention after the lockdown ends
- Fit with Meta's other products for children and with WhatsApp's privacy model
### Follow-up Questions
- How do you give parents oversight without weakening end-to-end encryption?
- Schools reopen and activity on kid accounts falls sharply. Is that a failure?
- Why should WhatsApp build this rather than leaving the space to Messenger Kids?
Overview: A product strategy question that asks how WhatsApp could win over children while COVID-19 lockdowns keep them at home. It tests how a PM defines the age group, works within minimum-age and parental-consent limits, prioritizes safe features for kids, parents and teachers, and measures growth with safety guardrails.
