The interviewer was not at all knowledgeable and filled with ego. He was not ready to accept the right answers. He just kept on arguing about senseless and illogical questions. He said that he has 5 years of experience so he knows everything. He doesn't even knew about q library functions and according to him .toString() method doesn't exist in JavaScript. His concept of two way binding in AngularJS was completely different and illogical. At the end of the interview he directly said to me that I am not selecting you because I didn't agree to his points and kept on giving the answers which were right but not as per his knowledge. I immediately walked out from newgen office. Very negative experience beacuse of a fool and dumb interviewer.
