First round HR person called me and ask about my thesis projects, but after second round interview, I decide to withdraw my application. The interviewer has no patience in clarifying questions and show no respect. After I correctly answered two simple probability questions, he asked me if I was using a computer to look for the answer. I was clearly insulted as I have been speaking to him to demonstrate my thought process, although he gave little feedback. I was applying for a quantitative research position, but they find an arrogant HR person to ask me probability questions. Very unpleasant interview process

First Interview: Talk about background with HR Second: Simple probability questions Third: Was told more probability questions, but got mostly programming syntax questions instead. Was told after the third interview they would contact me, but after I emailed them after a week, the informed me they had already moved on.
