Interview Prompt

We run an ad platform and want to know which month our retargeting campaigns brought in the most ad revenue. Return that month with its total revenue, its biggest single-impression revenue, and its average revenue.

Summary

Retargeting revenue. The peak month.

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
