Hello Yashwanth Kumar,
There are so many companies.
It really depends upon what you're capable of and what you're interested in.
If you want to stay in core Mechanical Engineering, you may try for big automobile industries like TATA motors, Mahindra, etc. You can join as a GET. And later could be made a permanent employee based on your performance.
But to be honest, it's really difficult to get in now a days if you're not campus recruited.
Also Mass recruiters today are Software Giants, which even recruit Mechanical engineering students.
If you're not very rigid with your field , you could take that as an option.
If for any matter you don't get placed easily, it's better to complete post graduation as you'll get an edge over your competitors.
Hope this helps :)
Best of luck!
