C.V Raman placement is slightly better than GITA. You can refer to MHRD NIRF rankings for that. Initially all the branches of engineering are allowed to sit for placement in core sector and that gives a different statistics in placement of mechanical engineering.
The core companies that visit campus often recruit less student and their salaries are attractive like Voltas 7 lpa, Tata Steel 8 lpa, Robert Bosch, Bosch Rexroth like that. But coming to the next side i.e it placement starts from 3 lpa by mass recruiters. On an average you can say placement of a core branch lies between 3 to 8 on an average
Best of luck.

The rank you mentioned is pretty good enough to take admission in CV Raman College of Engineering and mechanical engineering is quite a good branch. First of all, it's a core branch with many on campus training courses that will help you in future accompanied with well-equipped labs and center of excellence for practical concept clarification. I am only talking about CV Raman as I am a student here.
