Your question is Hypothesis Was Wrong. 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 your initial hypothesis was wrong. Choose a specific professional example where you made a prediction, discovered evidence that challenged it, and had to change your approach. Explain the stakes, how you validated the new information, what you did next, and what you learned.
