Natco Home Group interview questions

I am shocked by the behavior of the interviewer, wow. (NOT HR-I'm talking about a director)..incredibly casual / rude/ power trip. They picked apart / rolled their eyes at the way I said things (which has NEVER happened at other company interviews) and it seemed like they were enjoying the process of making me nervous. I was very excited about the opportunity, but after the interview, I absolutely do NOT want to work with this person.
