Interview Prompt
The ops team is preparing a regional performance recap from the orders log. For each region whose orders averaged more than 740 in profit apiece, show the region, its order count, and its total profit.
Summary
Every region keeps its own ledger. The totals set the order.
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
