SMS group Graduate Engineer Trainee interview questions

First there was an aptitude test. After that those who were selected, for them there was interview for engineering students. As i am in Electronics and Communication Engineering, i was the only one selected. And we all were called in the hall to come and wait for their turns for interview. First was the MCA students interview, for them only GD was to be held. As there interview was going on there was 1 person shortage in the last group so i was added to it. I had to give GD. After that, those who were selected then they had interview. But the interviewer was CSE based so i was asked coding related questions. My friends from EE were asked respective to their field. This is the thing that i didn't like about the company.

Initially I was asked to describe myself. Then I was asked some question on my project work. Then were questions regarding my interest subjects. Well noticable is that person stated my two answers reagarding IGBT wrong, well I spoke the same I have read in standard books. And after getting back I also cross checked on net, they were same as I answered. I didnt objected clearly in interview, because of aggressive mode of interviewer.
