Welcome to your interview.
The question is on your right: Accounts, Measurement, and KPIs. 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 many accounts did you manage, how were you measured, and what KPIs are you looking at for your customers?
