What this question tests

Judgment on whether and how to enter a mature, low-margin market using existing platform assets rather than building from scratch.

Question the premise first: food delivery is a low-margin, logistics-heavy business unlike the company's core software and ads model.
Identify the company's real assets: massive local business Pages, Groups, and existing ad relationships with restaurants.
Propose a lighter-weight option: an ordering and discovery layer integrated into existing local Pages and Marketplace, aggregating existing delivery providers rather than building an in-house fleet.
Reject building in-house logistics, which requires a fleet and driver network the company has no experience operating and is capital-intensive.
Propose monetization: ad placements for restaurants and a referral fee for orders routed to delivery partners.
Define success as order volume routed through the platform and incremental ad revenue from local restaurant advertisers.

Explicitly pushes back on the 'own delivery fleet' framing given the real lack of logistics competency, showing strategic judgment.
Proposes a realistic, asset-leveraging path, an aggregator on top of Pages and Marketplace, rather than an implausible full build.
Names a concrete monetization model, referral fee plus local ads, tied to the company's actual ad business strength.

Proposing the company build its own delivery fleet, ignoring the vast operational gap versus its actual capabilities.
Ignoring that this market is already saturated with entrenched, low-margin competitors.

Would you partner with an existing player or build independently?
How would you avoid channel conflict with delivery partners who are also ad customers?
