Interview Prompt
Billed cloud costs sit in `cloud_costs` and internal allocations in `cost_allocs`. What is the total spend for each region and service pairing across the two?
Summary
Region by region. Service by service. Where does the money go?
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
