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.
Suffering from the same problem, though it happens to me even in written exams - doing something for the sole purpose of being judged makes me incredibly uncomfortable, and I'm happy to be out of school/university and just have a job. It's all just infinitely easier and less stressful, even at the worst of times and with the worst of people.
