Interview Prompt
Your luxury marketplace processes sales events from thousands of seller boutiques across multiple countries and currencies. Each sale must be attributed to the selling boutique in real time, normalized to a common currency, and stored in a compliant data lake that protects buyer identity. Design the pipeline.
Summary
Every sale is real. The rate it was converted at depends on who is asking.
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
