Welcome to your interview.
The question is on your right: Real-Time Model Design in Simulink. 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.
How would you approach designing a model in Matlab/Simulink for a real-time system?
