Interview Prompt
A campaign only counts as earning in a year if its impressions brought in more than five dollars across that year. From `ad_impressions`, we need every campaign and year that cleared that bar, with how many people the campaign reached in that year.
Summary
Big-budget campaigns from last year.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
