Welcome to your interview.
The question is on your right: Mailing Cost Optimization Analysis. 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.
We noticed that the cost of mailing out notifications and policies has increased significantly over the past year at The Plymouth Rock. Given a dataset from our mail carrier, how would you tackle this problem?
