Interview Prompt
Our department scorecards show a single all-time average of the tracked metrics per team, so we can't see whether a department rose or fell from one fiscal year to the next. Rebuild it from `employee_metrics` as a year-by-year average for each department.
Summary
How each team's numbers moved, year over year.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
