Interview Prompt
AFRY's finance team bills clients each month for the hours consultants log against engineering projects, and a consultant's hourly rate gets renegotiated every few quarters. Model the time logs, projects, clients, and consultants so an invoice from last spring still reflects the rate that was in effect when the work was done, even after that rate has since changed. The same model should let finance total billed revenue per project per month.

- Get instant feedback and a hire/no-hire decision
