Interview Prompt

We're a mid-size online retailer selling about 50,000 SKUs. The BI team needs self-service dashboards to analyze sales by product category, customer segment, geography, and time period. We also need to track inventory levels by warehouse. Design the dimensional model.

Summary

One business. A thousand transactions. Only one layout survives the analytics layer.

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 data modeling solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
