What this question tests
Marketplace design skill within Meta's ecosystem: can you build a trust based lending marketplace leveraging existing social graph and Marketplace infrastructure.
How to approach it
- Define users: lenders with idle household items, ladders, tools, camping gear, and borrowers who need them briefly.
- Identify the core barrier, trust that items are returned in good condition, same as any peer lending product.
- Leverage Meta's advantage, the existing social graph and Facebook Marketplace, to default lending to friends and local community first, where trust is higher.
- Design mechanics: item condition photos, a small refundable deposit, and reputation tied to real Facebook identity rather than anonymous accounts.
- Start hyperlocal, neighborhood groups, before opening to strangers city wide, to build trust gradually.
- Define success as completed loans without disputes and repeat lending within the same local network.
What a strong answer includes
- Uses Meta's actual distribution advantage, the social graph, as the trust mechanism instead of building trust from scratch.
- Sequences rollout from friends and local groups to strangers, a sensible way to de risk a new trust based marketplace.
- Picks a dispute rate metric as the real signal of whether trust mechanisms are working.
Common mistakes
- Designing a generic anonymous listings marketplace that ignores Meta's social graph advantage.
- Launching city wide to strangers immediately instead of starting where trust is already higher.
Likely follow-up questions
- How would you handle a dispute over a damaged item?
- Would you charge fees, and if so, how would that affect adoption?
