I took the on campus interview this week. The interview itself was not difficult, but the interviewer was scary. From the very beginning when I was introducing myself, he seems disagreed with me. And when I was answering the interview questions, he was not smiling at all, playing his phone for some time and read emails for the other time. That made me nervous and failed to come up a solution for the final question. At last when I was asking questions, his answers were short and simple and it was embarrassing. And he ended the interview 10 minutes earlier.
