Welcome to your interview.
The question is on your right: Choosing Attribution Models. 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.
What marketing attribution models have you worked with, and how do you determine which model to use at Delta Air Lines?
