I recently had an interview with a company that involved 6 people interviewing me serially. That sort of thing is grueling in the best of cases. But this one went south with the third interviewer. He seemed to me be someone with something like Aspergers syndrome. He talked in a monotone, fidgeted constantly and was rocking back and forth. While I have no problem working with anyone technically competent, this person was clearly not capable of running an interview.
He asked a technical question to which I answered a more or less standard response. He told me I was wrong. Being a bit stunned (it wasn't a hard question), I asked him what he meant. He gave me a reply that was quite incorrect.
Now, in a normal interview situation if this occurs, I see it as an opportunity to have a conversation. I can explain my point and the interviewer can respond. You can find out a lot about an organization with this kind of interaction.
But in this case, the interviewer just kept saying I was wrong and never responded to my questions or gave an explanation why his answer's were correct except to say that they were. It was very troubling.
I didn't get the job. This might have been because of this interview directly but it certainly was at least partially the cause since I really didn't have much enthusiasm for the next 3 interviews. A company that would allow someone with social interaction issues run an interview is very problematic. I can't imagine who could have done well in that series of interviews given the circumstances.
