Welcome to your interview.
The question is on your right: Why This Role, Why Now. 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.
Why are you looking to leave your current role, and why does this opportunity make sense for you at this point in your career? Please be specific about what you're moving toward, not just what you're moving away from.
