Interview Prompt
A cloud FinOps platform records cost allocations against a team and a service, with many allocations per team. Find each team's total spend and its average spend across its services, keeping only teams whose total spend is under twice the average team total.
Summary
Twice the average is the ceiling. Find the teams comfortably beneath it.
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
