Designing a Chat-Based Storefront and Checkout Product Inside WhatsApp
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager at Meta, and leadership wants a new WhatsApp product named "Shops." Design it: explain what Shops does and why it belongs in WhatsApp, who it serves, what the core experience looks like for those users, what you would build first, and how you would know it is working.
```hint Decide what kind of shop it is
"Shops" could mean a marketplace where buyers browse many sellers, or a storefront each business runs inside its own chats. Choose based on how buying and selling already happen on WhatsApp, because that choice shapes the users, the features and the risks.
```
### Clarifying Questions
- Is the main goal revenue for Meta, more engagement in WhatsApp, or helping businesses already on WhatsApp sell more effectively?
- Should Shops build on WhatsApp's existing business tools, such as the WhatsApp Business app, or start as a separate experience?
- Which market launches first, and does it matter whether in-app payments are available there?
- Who is the seller: small businesses already taking orders over chat, or large brands using WhatsApp's paid business messaging?
### What a Strong Answer Covers
- A clear definition of Shops and a goal grounded in how people already buy and sell through WhatsApp chats
- Both sides of the transaction, buyers and sellers, with one seller segment chosen and justified
- Pain points in today's chat-based buying, mapped to specific features, with a prioritized first release and what is deferred
- Success metrics for both sides, including guardrails for spam, fraud and the private-messaging experience
- Risks specific to WhatsApp: end-to-end encryption expectations, payment availability by country, and trust between buyers and sellers who barely know each other
### Follow-up Questions
- How would you keep Shops from filling people's chat lists with promotional messages?
- A buyer pays and the seller never ships. Who is responsible, and what does the product do about it?
- Would Shops share listings with Facebook Marketplace and Instagram shopping, and what are the risks of doing so?
Overview: A product design question that asks a product manager to create Shops, a buying and selling product inside WhatsApp. It tests defining the product and its goal, choosing which sellers and buyers to serve, prioritizing a first release, and measuring success with guardrails for spam, fraud and private messaging.
