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

  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
