The interview, in my experience wasn’t that bad at all. I’ve also dealt with clients that ask similar questions and I felt they were actually pretty much right. The whole point was they were looking for someone who would be able to cut off a line of discussion and focus on the point at hand. You are never going to know everything they ask, and that’s okay, you have to admit that. Say you’ll get back to them after the meeting, but for now we should focus on X,Y and Z. I found the complete opposite to yourself and enjoyed the whole experience, I feel your attitude is quite negative, this should have been seen as an opportunity to show them who you are, not necessarily what you know, and it sounds like you were unable to do that, but Microsoft are known to hire the right people, not the right technical skill set
