Welcome to your interview.
The question is on your right: Understanding Interrupt Service Routines in Embedded Systems. 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.
What is the role of an Interrupt Service Routine (ISR) in embedded systems? Discuss how ISRs handle interrupts, their execution context, and their impact on system performance. What are some common challenges associated with ISRs?
