Design Google Cars
Published 3 October 2026
System Design¶
I was asked to design something like "Google Cars," similar to Google Flights, but for searching and comparing cars.
There were quite a few follow-up questions. Be prepared to discuss topics such as:
- Data modeling
- Classes / object-oriented design
- Database design
- ACID properties
- Design decisions and trade-offs
The interviewer kept building on the original problem, so being able to explain why you're making certain design choices is important.
