Welcome to your interview.
The question is on your right: Switch Debouncing Hardware and Software. 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 the phenomenon of switch bouncing and how you implement an effective debouncing algorithm in both hardware and software.
