Welcome to your interview.
The question is on your right: SDLC Perspective. 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 your favorite aspect of the SDLC, and why does it matter for delivering business value?
