Your question is Influencing Without Direct Authority. 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 needed to influence stakeholders to change direction or support a decision when you didn’t have direct authority over them. What was at stake, how did you bring them along, and what was the outcome?
