The interviewer had started off very condescending. He seemed to have a chip on his shoulder about people who have a higher degree and began the interview by saying, "I don't have a fancy degree like you, so can you walk me through your CV?". It was then followed by, "People with your background, tend to say they will do everything that is asked of them, and once they're hired, they don't. So when I went on to answer the question, he interrupted me and said, "So if I asked you to clean the toilet, or wash my car, would you do it?" ... All this, with HR sitting right next to him! I am not sure if he thought he was being funny, but it was the strangest and a disrespectful experience.
