How I would respond to a question I don't know is that I will turn the question into a small conversation and try to get different point of views and try to break the question down to the best of my ability. Even if I don't have that exact answer, I will try to break the question down as I said before and ask different questions as well as that question to try to get the answer to the best of my ability. I wouldn't actually say I don't know because that's not something that you would want to say in a situation as far as being at work. So I would say that let's try to get point of views, different point of views that relates to the question and then get a better understanding and we'll try our best to get an answer. So that's what I would do.
