M.Tech

There are very few Institutions that offer M.Tech in Mechatronics in India. As it's a young branch, investment in M.Tech in India would be useless but outside India such as Germany, USA, UK, Russia you'll find there is a huge demand for mechatronics engineers with good knowledge. Even the companies which manufactures the medical machinery needs the mechatronics engineer.

Dear Raghib,
If you're aspiring to make a good career in IT, I will strongly suggest you to go for B.Tech-M.Tech combo. If you posses high skills in programming, then there is no problem pursuing it in an average college.
All the best for your future.

Now a days, lot of colleges offer M.Tech, but if you really want to get white collar job, you must get admission in top universities, where you can get on campus placements.
M.Tech degree is just useful for future in your career promotions, which will hike your salary.
