Interview Prompt
We need to track what our subscribers are watching. This data feeds everything from our recommendation models to operations dashboards that monitor playback quality in real time. Design a data pipeline for our viewing events.
Summary
Someone is watching. Capture everything.
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
