What is minimum percentage in B.Tech needed to get a job in mechanical engineering?
For getting a job,you don't need percentage,all you need is skills and expertise in your field.
But you should maintain atleast 65% in acedemics, that would e helpful.
Your skills, experience and qualification does matter in your placement but not the percentage exactly.
So try to get into good company and get a decent placement, gain some experience and then target huge brands.
Good Luck.
