Tailor WhatsApp to Seniors, Families or Businesses: Pick a Segment and Design for It
Company: Stripe
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Choose one of three groups (senior citizens, families or businesses) and design a version of WhatsApp that serves that group well.
```hint Make the choice part of the answer
Compare the three groups on how large and painful their unmet needs are, how well WhatsApp serves them today, and what WhatsApp gains. Commit to one, then design within WhatsApp's commitments to simplicity and end-to-end encryption.
```
### Clarifying Questions
- Should the answer add features inside today's WhatsApp app, or is a separate app on the table?
- Which markets should I design for: countries where WhatsApp is the default way families and businesses talk, or markets where it is one messenger among several?
- What does WhatsApp most want from this work: engagement, user safety or revenue? That affects which group is the strongest pick.
- Is end-to-end encryption a fixed constraint for every feature?
### What a Strong Answer Covers
- A reasoned choice among senior citizens, families and businesses, comparing unmet need, how well WhatsApp serves each today, and the payoff for WhatsApp.
- Sub-segments and concrete pain points within the chosen group.
- A prioritized feature set with a clear first version that keeps WhatsApp simple for everyone else.
- How each feature respects end-to-end encryption and user privacy.
- Success metrics and guardrails, including how to measure a group that WhatsApp may not be able to identify directly.
### Follow-up Questions
- Why not the other two groups? What would change your choice?
- One of your features needs a signal that end-to-end encryption hides from WhatsApp's servers. How do you deliver it without weakening encryption?
- How would you keep your design from adding clutter for users outside the group you chose?
Overview: A product design prompt that asks the candidate to pick senior citizens, families or businesses and design WhatsApp around that group. It tests justifying the segment choice, finding concrete pain points, prioritizing features that keep the app simple and end-to-end encrypted, and setting success metrics with guardrails.
