Nous Infosystems Software Engineer - Java Developer interview questions

Not really sure still. I had technical round, then managerial round and then suddenly one more technical round once i submitted all my documents. I wasn't really sure why I am being asked for technical round after managerial one. Questions were all relevant but i am not really sure about the intent of the interview as I mentioned above. I am giving interview on a holiday with a free mind and to basically learn from that experience. The interviewer was all judgy and only trying to find a path where i couldn't answer. Worst thing was, he asks a question, i am answering it and suddenly when he knows i am going to answer, he is interrupting and asking a question without letting me stop. When it happened more than 10-15 times, i had to stop and say that i am not interested anymore in the opportunity. I would prefer a workplace where the crowd is better than me atleast with basics. I myself have taken interviews and got never received the kind of feedback from any candidate that i am giving for this person. Only thing is that the questions were relevant and that's the reason i waited long enough in the interview and was answering with all my good intent but this habit of being in a hurry and finding only the things we don't know, reduced my intent of proceeding forward with the interview.
