Interview Prompt
We keep a cost allocation table where each row is one service charge booked to a team. For each team, surface its three highest-cost charges, showing the team name, a label that combines the service and its region, and the amount.
Summary
The heaviest bills each team carries.
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
