Interview Prompt

The marketing team is auditing ad campaign performance before next quarter's budget allocation. For each campaign, they want to see the click-through rate as a percentage of impressions, the total revenue attributed to the campaign, and how many impressions were served. Only surface campaigns with more than one in five impressions resulted in a click , anything below that isn't worth renewing. Rank from highest click-through rate to lowest.
