What this question tests
Applying a tech company's actual strengths, mapping and AI, to an unfamiliar physical infrastructure product.
How to approach it
- Clarify why Google would build this: likely as a Google Maps and payments integrated smart parking product, not a physical garage builder.
- Identify the core pain points of parking: finding an open spot, paying without cash or an app switch, and navigating exit without a ticket.
- Segment users: daily commuters wanting reserved recurring spots versus one off visitors wanting quick, easy parking.
- Prioritize the search and pay pain points, since they're the most frequent friction across all users.
- Propose real time spot availability shown in Google Maps, license plate based entry and exit with automatic payment, and a reservation option for commuters.
- Define success as average time to park, from arrival to parked, and payment dispute rate.
What a strong answer includes
- Frames the product around Google's real strengths, Maps and payments, rather than physical construction.
- Distinguishes recurring commuters from one off visitors, since their needs differ meaningfully.
- Gives an illustrative number, for example assuming average park time drops from 8 minutes searching to 2 minutes with real time availability.
- Addresses payment friction directly with license plate recognition, a concrete, checkable mechanism.
Common mistakes
- Focusing on the physical garage structure or architecture instead of the software and data layer Google would actually build.
- Ignoring privacy concerns around license plate tracking and camera based entry systems.
Likely follow-up questions
- How would you handle privacy concerns with license plate recognition?
- How would this integrate with existing city parking infrastructure and regulations?
