Interview Prompt
We need to track how much time employees spend in each application. HR wants daily summaries of time-per-employee-per-application, and wants to flag any employee spending more than 10 hours/day in a single application. Design the schema to capture this data.
Summary
Every minute tracked. Every app accounted for.
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
