Other than IIM Shillong, Tezpur University is the only institute that uses CAT scores for admission in MBA. They also accept MAT scores. I have a few friends who attended TU for their MBA and according to them, it is a decent institute for pursuing your MBA.
A lot of recruiting companies visit the campus placements each year. In the last placement drive, the salary packages offered were in the range of 3.5-10 LPA. Major recruiting companies on TU are Wipro, HCL, ICICI, Axis Bank, etc.
