Your question is Explaining Your Career Move. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about why you wanted to leave your previous role and what you achieved there. I am looking for a candid explanation of your motivation, along with specific evidence of the value you delivered before deciding to move on. Please focus on your own actions, measurable outcomes, and what you learned, without criticizing your former employer or colleagues.
