Your question is Owning a Broken Financial Model. 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 audit a financial model that was returning an error or producing inconsistent calculations. How did you isolate the issue, communicate the risk, and get the model back to a reliable state?
