What this question tests
Tests product design applied to adapting a company's core competency (social graph, sharing) into a new vertical, with a clear user and monetization angle.
How to approach it
- Identify the user: travelers who want trip inspiration, planning help, and social proof from friends who have been to a destination.
- Identify pain points: fragmented planning across many apps, and lack of trusted, personal recommendations compared to generic reviews.
- Propose the core feature: a trip-planning hub where users can see friends' past trips, save destination ideas, and co-plan an itinerary with friends in one place.
- Leverage Facebook's existing assets: the social graph (friends who traveled there), Groups for destination communities, and Marketplace-style booking integrations.
- Prioritize an MVP: start with a shareable trip board that pulls in friends' check-ins and photos, before adding booking functionality.
- Define success: trips planned collaboratively with at least one friend, and conversion to actual bookings if monetized through travel partners.
What a strong answer includes
- Anchors the idea in Facebook's unique asset, the social graph, rather than building a generic travel app that ignores what Facebook actually has.
- Chooses a narrow MVP (a shareable trip board using existing friend data) instead of building full booking and payments on day one.
- Names a monetization path (travel partner bookings) consistent with how Facebook already monetizes Marketplace-adjacent features.
- Defines success around collaborative planning specifically, since that is the differentiated value versus existing travel apps like TripAdvisor.
Common mistakes
- Designing a generic travel app that does not meaningfully use Facebook's social graph.
- Skipping a monetization or success metric and treating this as a feature with no business goal.
Likely follow-up questions
- How would you prevent this from becoming just another underused Facebook feature like past product launches?
- How would you measure success differently for solo travelers versus group trips?
