What this question tests
Marketplace design skill: can you solve the trust and logistics problems specific to peer to peer lending of physical appliances.
How to approach it
- Define users: lenders with idle appliances, like a drill or a pressure washer, and borrowers who need one occasionally.
- Identify the core pain points: trust that the item works and is returned undamaged, and the hassle of pickup or delivery.
- Prioritize trust first, since without it neither side will transact, ahead of discovery or pricing.
- Design the solution: verified listings with condition photos, a deposit held until return, and ratings tied to real identity.
- Address logistics with a simple local pickup flow first rather than building delivery infrastructure at launch.
- Define success as completed lends without disputes and repeat lending rate.
What a strong answer includes
- Treats trust as the core design problem, not an afterthought bolted onto a generic listings app.
- Starts with local pickup only, a reasonable scoping decision to avoid overbuilding logistics for an unproven market.
- Picks a dispute rate metric, since it directly measures whether trust mechanisms are working.
Common mistakes
- Jumping straight to building delivery logistics before proving demand exists.
- Ignoring damage or non return risk, which is the biggest reason peer lending marketplaces fail.
Likely follow-up questions
- How would you handle a dispute where the appliance came back damaged?
- Would you start in one city or category first, and which one?
