Your question is Order Scheduling with Worker Proficiency. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Given products requiring different processing steps, variable time per step, specific workstations, and workers with different proficiency levels across steps, design an algorithm to maximize total score by completing orders within deadlines.
