Interview Prompt
Our customer support team needs to see a customer's current address and their full address history for regional sales analysis. How would you design a schema that handles address changes?
Summary
People move. Sometimes twice in a month. How do you remember where everyone was, and when?
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
