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.
