Welcome to your interview.
The question is on your right: Attribution Model Choice. 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.
Explain the difference between first-touch, last-touch, and multi-touch attribution models, and which would you recommend for a multi-channel mortgage campaign at Santander Holdings USA?
