Welcome to your interview.
The question is on your right: Payback Periods in Scaling. 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 account for payback periods when scaling ad spend on paid acquisition channels for Heliosx Group?
