Welcome to your interview.
The question is on your right: Proving ROI for Brand Awareness. 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.
If a regional director asks you to prove the ROI of a brand awareness campaign at Randstad Digital Portugal, what metrics and methodologies would you present?
