Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Facebook Marketplace lets people buy and sell items with others nearby. What would you change to make it better, for which users, and why?
```hint Walk one sale
Trace one item from the moment its owner thinks about selling it to the moment a buyer takes it home, and note where each side stalls or gives up.
```
### Clarifying Questions
- What should the improvement achieve: more completed sales, more engagement, more revenue for Meta, or is the goal mine to set?
- Should I design for one country or market, or for the product as a whole?
- Are business sellers and dealers in scope, or only individuals selling to one another?
- Should high-value categories such as vehicles and home rentals be included, or only everyday goods?
### What a Strong Answer Covers
- A goal for the improvement and why it matters to Meta
- Users on both sides of the market, with a chosen segment and the reason for it
- Pain points along the selling and buying journey for that segment, ranked
- Prioritized solutions, a first version and what is deferred
- Success metrics with guardrails, and risks such as fraud, safety and an imbalance between buyers and sellers
### Follow-up Questions
- After launch, buyers send more messages, but sellers complain about lowball offers and people who never show up. What do you do?
- How would you know your change grew the marketplace rather than shifting sales from some sellers to others?
- Would you charge for any part of your solution? Why or why not?
