Welcome to your interview.
The question is on your right: 30-Day ROAS Pivot Across Channels. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you structure a pivot table to compare the return on ad spend (ROAS) across multiple marketing channels over a rolling 30-day period?
