What this question tests
Tests marketplace product design within a social platform: can you identify trust as the central design challenge for connecting strangers for paid local work.
How to approach it
- Clarify the user: someone on Facebook looking for a local contractor who currently relies on unstructured Groups posts or Marketplace listings.
- Identify the core pain point: lack of verified reviews, unclear pricing, and no structured way to compare contractors for the same job, unlike Thumbtack or Angi.
- Prioritize a structured request-and-quote flow: users post a job, verified nearby contractors submit quotes, and requesters compare profiles before choosing.
- Address trust directly: contractor verification and a review system tied to real completed jobs, since trust is the core barrier to a stranger transaction.
- Leverage Facebook's unique advantage: showing if a contractor is already known within local Groups or mutual connections, a real differentiator over a cold-start app.
- Define success as completed-job rate and repeat usage from both contractors and requesters.
What a strong answer includes
- Identifies trust and verification, not discovery, as the central design problem, correctly diagnosing what makes local-services marketplaces hard.
- Leverages a genuine Facebook-specific advantage, mutual connections and local Groups as a trust signal, differentiating this from a generic marketplace.
- Proposes a structured quote-comparison flow rather than an unstructured post-and-hope model like current Marketplace listings.
- Picks completed-job rate as the core metric, reflecting actual transaction success over post or view counts.
Common mistakes
- Designing a simple listings feature without addressing trust and verification, the actual core problem in stranger-to-stranger local services.
- Ignoring Facebook's unique social-graph advantage that a standalone marketplace app would not have.
- No metric tied to actual completed transactions, relying on posting or browsing volume instead.
Likely follow-up questions
- How would you verify contractor legitimacy without creating too much friction to join?
- How would you handle a dispute between a requester and contractor after a job goes badly?
- How would you compete against dedicated platforms like Thumbtack that already have this trust infrastructure built?
