Disclaimer: I haven't read TFA yet (will look at it later). But I've interviewed software people, detected anxiety sometimes, and made a mental note to not hold it against them. They're not interviewing for sales jobs, they are nerds, and it's fine for nerds to be shy introverts, especially around strangers.<p>If you're interviewing someone like that, try to give them a little breathing space, and maybe even tell them that you are noticing the nervousness and that it is ok. If you're being interviewed, I think it is ok to say you are a little bit nervous, take a few deep breaths to calm yourself down, etc.
