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.

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write your pipeline design solution with real code execution
4. Get instant feedback and a hire/no-hire decision
