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. The same team sometimes appears under different letter casing, so treat those as one team and list each once, smallest total first.
Summary
Twice the average is the ceiling. Find the teams comfortably beneath it.
