Welcome to your interview.
The question is on your right: Substitute Teacher Routing and Assignment. 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.
Implement an algorithm to find the most efficient routing or assignment for substitute teachers based on location and certification constraints.
