Some of my friends attended Gauhati University. According to their experience, the university offers a decent MBA program. The degree course is not that competitive, but the course curriculum is up to industry standard.
Gu offers decent hostel accommodation. The campus life is also quite good. According to the recent placement highlights the highest CTC offered was 5 LPA. Some of the major recruiters that visit the campus placement are OIL, CocaCola, etc.
