Interview Prompt
Our 500,000 rental vehicles stream telematics continuously while a reservation system records rentals and service centers log maintenance, and no view spans all three. Design the pipeline and warehouse that unify the three sources on vehicle id and serve each consumer at its own freshness.
Summary
Every vehicle is reporting. Every rental matters.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
