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, sales channel, and time period. Design the dimensional model.
Summary
One business. A thousand transactions. Only one layout survives the analytics layer.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your data model on the schema canvas: tables, keys and relationships
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
