Interview Prompt

The ad_impressions table logs every ad shown along with the revenue it earned. Return the campaigns whose revenue booked by the mid-year cutoff adds up to more than $4.50.

Summary

Impressions are vanity. Conversions are sanity.

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
