Neighborhood borrowing library product design: segments, MVP, trust and metrics
Company: Meta
Role: Product Manager

Difficulty: medium
Interview Round: Other
Design a lending library that serves a local community. Describe who it is for, which problems it solves for them, how borrowing and returning would work, what you would build first, and how you would measure whether it succeeds.
```hint Scope it, then choose whose problem to solve
Whether the library lends books or everyday items such as tools and toys, and whether an organization owns the stock or neighbors lend their own things, changes which problems matter most. Fix a scope, then focus on the group of members whose need is sharpest.
```
### Clarifying Questions
- What does the library lend: books and media only, or also physical items such as tools, kitchen appliances, camping gear and toys?
- Is this a physical space, a digital service that helps neighbors lend to each other, or a combination? If digital, is it a standalone product or a feature inside an existing community or social app?
- Who owns the inventory: the library itself, stocked through donations or purchases, or members who keep their items at home and lend them out?
- What is the main goal: access for people who cannot afford to buy, less waste, or stronger ties between neighbors? Is it free or funded by member fees?
### What a Strong Answer Covers
- A stated scope and goal, with a reasoned choice between a physical, digital or hybrid model.
- Users on both sides (borrowers, and the contributors or volunteers who keep it running), a chosen focus segment, and that segment's specific pain points.
- Prioritized solutions with a clear first version that covers finding an item, reserving it, picking it up and returning it, and handling late, damaged or lost items.
- Success metrics built around completed loans, with guardrails, plus the main risks and how to reduce them.
### Follow-up Questions
- In the first months, many items come back late or damaged. What would you change in the product or the rules?
- How would you fill the catalog before launch so that the first borrowers find what they need?
- How would your design change for a rural community where members live far apart?
Overview: A product sense question asking how to design a lending library for a local community. It tests scoping what is lent and whether the service is physical or digital, choosing a user segment, handling trust and late returns, prioritizing a first version, and defining success metrics.
