How important is organization to you?
The interviewer wants to know you can handle the workload. Be careful, though. You don't know how unimportant/important organization is to the interviewer, so you should give a balanced answer.
Focus on the fact that organization is important and that you try to be as organized as possible. However, you should acknowledge that situations arise when organization goes out the window to rush to meet a deadline. Let them know that you are generally organized but can be flexible if needed.
Avoid saying you are either meticulously organized or not organized at all. The interviewer wants to know if you can stay organized while remaining flexible.
"I believe organization is very important, so I try to know where important documents and other items are at all times. I also understand that sometimes things can get crazy when we are rushing to meet a deadline. If I get disorganized, I take a few minutes to organize my files and my thoughts. I feel that if I take just those few minutes to do that, I will save time later."
