Interview Prompt
We reconcile each team's budget allocation against the actual cloud charge for the same service in the same billing month, prorating every pairing to an hourly figure by multiplying the allocated amount by the actual cost and dividing by the hours in a year. Return each service with its total prorated cost, highest first, keeping only services whose total comes out positive.
Summary
Allocated on paper. Spent for real. Reconcile the two.
