Your question is Motivation and Fit. 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 what you dislike about your current employer and how it shaped what you want next.
I am looking for a specific, professional example rather than a list of complaints. Explain what you tried to improve, what you learned about your own working preferences, and why PhysicsX is a thoughtful next step rather than simply an escape. Keep the focus on observable facts, your own choices, and the type of environment where you can contribute effectively.
