Your question is Building a Model From Ambiguous Inputs. 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 build or improve a financial model when the inputs were incomplete, messy, or changing. How did you decide what modeling approach to use, how did you validate your assumptions, and what business outcome came from your work?
