What this question tests

Basic product design leveraging Facebook's existing social graph and local business presence for a discovery use case.

Define the user: someone looking for a trusted local service and wanting recommendations from people they know, not strangers online.
Identify Facebook's advantage: existing local business Pages, neighborhood Groups, and a social graph showing which friends have used a service.
Propose a local services search that surfaces businesses recommended by friends or active in relevant Groups, ranked by social proof.
Add a request flow letting users post a need to their network or a local Group and get responses aggregated in one place.
Define success: request to booking or contact conversion rate, and repeat usage for future local needs.

Leverages Facebook's actual differentiator, the social graph and local Groups, rather than building a generic directory clone.
Uses social proof as the core ranking signal, which competitors without a social graph cannot replicate.
Proposes aggregating scattered Group post requests into one structured flow, solving a real observable pain point.

Designing a generic local search or directory feature with no use of Facebook's social graph advantage.
Ignoring that this behavior already happens informally in Groups, missing a chance to formalize and improve it.

How would you handle fake or paid recommendations gaming the social proof signal?
How would you monetize this without alienating users who came for organic recommendations?
