My brain completely ****ed me in my interview today. I was prepared, ready, and confident, but as soon as I sat down my brian just said, "**** you, I'm out." And every answer I gave I was struggling and stumbling. I had a VERY EASY whiteboard problem to solve and I just couldn't do it, I gave the wrong answer like 3 ****ing times. Then the instant it was over and I walked out the door a flood of a thousand well-versed and knowledgeable answers popped into my head. I don't know what happened, it was like I had a stroke or something. This has never happened before, I am so mad at myself.
