The worst interview experience in my life. I developed a batch system in my current project. He asked me about it and I was explaining the system. He interrupted me and asked me that is the system real time. I said no. He said He wants real time system. If he wants real system he should build it or he should ask me what I will do to make it real time. He asks something and within 5 sec, he interrupts me then he asks the same question after 10 min. I felt to walk away from interview room. I think that interviewer is mentally challenged. I felt that I wasted 1 day in my life. The interviewer was attacking me and interrupting me and frustrating me. The manager was nice though. I learned something new from every interview and I also learned something from this interview which is sometimes mentally challenged people also interview.
