Your question is Incomplete Data Situation. 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).
Walk me through a time when you didn't have a complete data set and what you did to address this issue. Explain what information was missing, how you assessed the risks of proceeding, and how you obtained or validated additional information. I am looking for a specific example that shows sound judgment, prioritization, and ownership rather than a hypothetical answer.
