Welcome to your interview.
The question is on your right: CI vs CD vs Continuous Delivery. 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.
Differentiate between CI, CD, continuous delivery, and continuous deployment.
