Interview Prompt
We run a music streaming service and our premium subscribers are cancelling at 8% a month. Design a data model that lets the retention team compare how listening habits, playlist activity, and subscription history differ between members who churned and those who stayed in the weeks before a cancellation.
Summary
Subscribers are leaving. The data knows why.
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
