One of my close friends recently got admission to NITIE Mumbai. In the interview, he was asked mostly about his final year engineering project and his work experience, education, and about his skills. To clear your interview you will have to prepare very hard and will have to practice a lot. Here are a few things you should do for your preparation.
NITIE has a mock admission process called B-Cube. This will give you an idea about the GD and Interview.
