He's right. Maybe you didn't get weird questions, but I got "Circle or square? Why? Oh and take your time and think about it, if you need to." <--WTF? lol Same guy also asked me if I would marry a doctor or someone less educated than me. 🙄 He was a total pig, for lack of a better word. I knew him prior to the interview as well because I had done summer research there the summer before. I didn't call him out and just responded calmly and maturely. I took his questions just as seriously as if he asked me why I wanted to be a doctor.
Needless to say, I was interviewing for doctoral programs at the same time and was shocked at the difference in interviewing styles. There was much less BS involved for the doctoral interviews. They were very "to the point."
But yes, I do think the interviewing portion can make or break you.
