Welcome to your interview.
The question is on your right: Backward Compatibility for Firmware Updates. 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 do you ensure backward compatibility when updating firmware or communication protocols on legacy hardware devices for Teledyne Flir?
