There is no scope for M.Tech in material science and engineering. It is suggested not to opt for this particular course at any of the engineering colleges in India.
No colleges have produced any skilled Material Science engineers. The curriculum is 40 years old and there are no private electrical companies in India. Most importantly, there is absolutely no demand for material science engineers in India and it should not be taught in India.
The current M.Tech programs running in the country are a scam. You will not be able to find any demand in the industry. The syllabus of M.Tech is forced upon engineers to run the GATE coaching industry.
99.99% of M.Tech graduates do not get the desired salary and respect of a researcher. The average income is only 2-3 LPA which is very low. Most of them become clerks in the service-based industries.
