Welcome to your interview.
The question is on your right: Optimize Code for Real-Time. 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.
Given a piece of code you wrote for a past project, how would you optimize it for a real-time system at Nio Robotics?
