Tech Mahindra Linux/Windows Administrator interview questions

The Interview was at Chandivali Mumbai office. We were made to wait more than 4 hours. Interviewer was not at all interested, he was staring here and there and not at once did he made an eye contact. He was smiling mockingly when I was talking about my work experience as if I am nothing and he is an expert. After waiting for so long it was a very humiliating experience especially if you are an experienced candidate of almost 4 years. I have given interview at a lot of reputed and big companies and this was my worst experience.
