Interview Prompt
We operate a fleet of 500,000 rental vehicles across thousands of locations globally, with each vehicle emitting continuous telematics data alongside rental transactions from our reservation system and maintenance events logged by service centers. Our operations team currently has no unified view across these three sources and is flying blind on fleet utilization and vehicle health. Design the end-to-end data pipeline and the warehouse architecture that serves it.
Summary
Every vehicle is reporting. Every rental matters.
