Welcome to your interview.
The question is on your right: Marketing ROI Excel Modeling. 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 do you structure an Excel model to analyze marketing campaign ROI, and what formulas do you rely on most?
