Interview Prompt
The marketing team is auditing ad campaigns before next quarter's budget is set, and only campaigns converting impressions to clicks at a strong rate are worth renewing. Surface those campaigns with their click-through rate, the revenue they brought in, and how many impressions each got, highest click-through rate first.
Summary
A click is the only vote that counts.
