I think we end up with same interviewer he asked me the same thing ...about Texas..but then he noticed I moved around a lot for my education...so he mention oh..from your country..to U.K to Atlanta to Texas and now Arizona.....I told the same thing about state school ....and told him my state school has not invited me for interview yet.....I think over all he was a serious person that's why you felt he had attitude ...I noticed he had same face from begging to end ...at least he made sure I wasn't nervous...so nothing to worry about it was pretty laid back interview ..I just felt it wasn't long enough to show who you are...kind of felt rushed.
School no doubt hi-tech.
