I completed my b.tech in ece(2014) but I'm not getting job what should I do now

Have you tried work experience ( working for free ) somewhere to get some experience and even references so when you actually try to get a paying job you are more likely to be successful.

You find any job you can. There are people in America with Masters Degrees, working at fast food places. You find a job,and keep working at finding new jobs

You take what you can get while you look for what you want.
