Welcome to your interview.
The question is on your right: Forecasting Variable Costs. 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.
Explain your approach to forecasting variable costs at Align Technology in an environment with fluctuating production volumes.
