Your question is Learning a New Business Domain. 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 get up to speed quickly on a new business domain or operational process at the start of a project. How did you learn it, who did you involve, and how did you make sure your analysis was actually useful to the people running the process?
