My interviewer was really cold and serious. She didn't interview me like I was a person, but more like I was a machine - she just wanted me to spit out the answers to her pre-made list of questions. The interview lasted approx. 30 minutes. She didn't respond to any of my questions. Just went on to the next question. At the end, I had no idea what she thought of me but I don't care because even if the company ends up calling me back, I do not want to work for them.
