Interview Prompt
Our users stream music on phones, desktop apps, smart speakers, and web browsers. We want to show artists and labels near-real-time stats on how their tracks are performing, and we need a historical record for royalty calculations. Design a data pipeline that collects listening events from all our device types.
Summary
Phones, tablets, laptops. And some of them report late.
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
