Welcome to your interview.
The question is on your right: Financial Model for New Service. 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 you were asked to build a financial model for a new service offering at Publicis Groupe, what assumptions and inputs would you consider?
