"Being a good programmer has a surprisingly small role in passing programming interviews." "And that just says it all, doesn't it?" An interview is for both prospective employer and potential employee to meet and find out about each other. If you as a candidate notice something you don't like during the interview (including the interview itself), that already is a valuable information for you, as you already may assume things based on it (like, what kind of people you may find past the in-process interview as they all more or less were filtered in by it). So you can always stop and say "thank you" and walk away without wasting more time. You'll allow yourself to stay longer only when the interview's quality warrants it.
