Interview Prompt
Design the pipeline that carries telemetry from millions of connected vehicles to two teams: safety analytics, which acts on individual braking and ADAS events, and predictive maintenance, which reads aggregated trends. Raw coordinates may be kept only for the regulatory window, while analytics reads a coarsened location.
Summary
Every vehicle is a sensor. Deploy the pipeline to catch it all.
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
