Hello dear!!! 

There are many ways that one can get a core job on basis if a mechanical engineering degree. The most taken way is via getting a job under college placements section. And If you clear gate with an exemplerary score then with that score you can directly contact core companies in your area and show your command over subject by that core gate certificate.
