What this question tests

Applying a tech company's actual strengths, mapping and AI, to an unfamiliar physical infrastructure product.

How to approach it

  1. Clarify why Google would build this: likely as a Google Maps and payments integrated smart parking product, not a physical garage builder.
  2. Identify the core pain points of parking: finding an open spot, paying without cash or an app switch, and navigating exit without a ticket.
  3. Segment users: daily commuters wanting reserved recurring spots versus one off visitors wanting quick, easy parking.
  4. Prioritize the search and pay pain points, since they're the most frequent friction across all users.
  5. Propose real time spot availability shown in Google Maps, license plate based entry and exit with automatic payment, and a reservation option for commuters.
  6. Define success as average time to park, from arrival to parked, and payment dispute rate.
