The purpose of an interview is not to root out a bullshitter but to find someone you can work with. If that guy doesn't know about TCP/IP, move on to the next topic. If the guy has poor attitude, be polite. Just don't waste time with making fun of the candidate, it does not reflect well on interviewer and company. For what we know, the guy may well have been employing "test-taking strategies", and he may have been led down the garden path by the interviewer. There's far too many posts in Rachel's blog where she goes on about "the one", who knows much better already, and here she channels the asshat that she complains about when she encounters him at work.
