If it were, I'd understand. I'm quite aware and accommodating of autism spectrum issues. But the guy was just arrogant and acted with an unwarranted degree of familiarity towards me just because we're from the same country. I'm of the opinion that where the candidate was born should buy them absolutely nothing. Many interviewers don't share this opinion BTW. Some will give overt preference to their compatriots, possibly on the account of "cultural fit". It didn't help that he didn't do well on the coding question either. In the end I only mentioned the "fucks" in passing in my feedback, and disqualified him on technical merit.
