Interview Prompt

Customers move. We need to know their current address and their full address history, including when they moved in and moved out of each one. Design the schema.

Summary

They moved. The data stayed behind.

How This Interview Works

  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
