When people are actively watching me to judge me, my brain just goes blank. It's happened to me almost every time in technical interviews where I was asked to solve a problem in front of the interviewers, and it's happened to me at school too in oral examinations. Written exams were not a problem. This never happens in normal work, even when working under pressure with a deadline that has to be met and not enough time to make it. It's just a completely different setting and purpose. In one case I'm solving a problem for the sake of being judged and that judgement may impact my whole life for the coming years. In the other case I'm solving a problem because there is a practical need for it and I'm just doing my job. It has nothing to do with being a good programmer or not, it has nothing to do with my actual ability to solve a problem either.
