Your question is Balancing Speed and Accuracy. 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).
How do you balance the need for speed with the need for accuracy in an ad-hoc request? Explain how you clarify the request, assess the risk of being wrong, choose an appropriate level of validation, and communicate assumptions or limitations. Focus on a specific example and describe the outcome.
