One of my friends got admission through CAT. He was initially on the waitlist but was eventually accepted. According to him the college itself was a fantastic experience. Here is some of the information I gathered from him, which might be useful to you.
Finally, he mentions that his life at NITIE was really exciting. He got to learn about the real dynamics of business and the corporate world. It groomed him to be a confident person. Overall his 2 years of experience at NITIE were really satisfying.
