Hello,

hey there.. well there are two important things to consider here:

1. You can  stop thinking of doing BE/BTech and go ahead look for internship opportunities in mechanical/automotive companies.
You will find more contacts and opportunities that way.
Internship is the key to, knock up a good job.
However Your starting salary might be less, as companies have pay scales that are designed taking your qualification into count.

2.On the other hand, if you DO go ahead and do BE/Btech. Your knowledge is going to improve, you will get 4 years and multiple opportunities to gain some basic skills in your domain.
However, You are NOT guaranteed a job even if you do BE. Just that your starting salary would be a little higher.


personally, if i was in your shoes, I would go with the first point.
If that did not work out, I would definitely start a business of my own.
Its difficult to setup and grow, but a business is any day better than a salaried job.
