Welcome to your interview.
The question is on your right: Stack vs Heap in Embedded. 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 difference between stack and heap memory allocation in embedded applications, and why dynamic memory allocation is often avoided in safety-critical systems.
