Welcome to your interview.
The question is on your right: Predictive Supply Chain Model Design. 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 we want to optimize the supply chain logistics for a physical commodity like minerals or oil at Koch Minerals & Trading, what data sources would you look for, and how would you structure the predictive model?
