Interview process was walkin. There were a lot of people and they were all categorised and process was good. I reached early so that i can get free early but it took complete day for the process

They have scheduled the interview from morning to noon,but they didn't schedule for particular time. The HR was not interested but thought to go ahead.I got a call around noon and she asked that can we start interview. She asked me to introduce myself.I was telling about myself but she didn't give a positive response. And then I had to discontinue the interview process as she felt that I was not prepared and she was not willing to ask the further questions .
