Your question is Lost Deal and Lessons. 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).
Can you tell me about a deal that you lost, why you lost it, and what you learned from it?
Answer with one specific customer opportunity and explain the sales process, stakeholder dynamics, qualification gaps, and your personal accountability. Focus on what you changed afterward and how that learning improved subsequent deals.
