Your question is Pivoting Under Changing Requirements. 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 a time you had to change your technical approach because requirements shifted after you were already in motion. How did you decide what to keep, what to rework, and how to communicate the pivot to the people depending on you?
