Interview Prompt

A media analyst wants a leaderboard of ad campaigns by total spend, built from `ad_impressions`, where each clicked impression records what the advertiser paid in `revenue`. Hand back the top of that board.

Summary

Two campaigns. Most of the budget.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
