M.Tech Scope

1. Metallurgy is an old field of science and it's an unconventional field of engineering, which students generally don't prefer because they think this field is not much in demand.
2. Actually, this field is the mother of every other field. Just imagine the world without metals and non-metals. It's unimaginable. Modernization of the human race started due to discovery in this field. The big machines (mechanical), automobiles, chemical engineering, etc.
3. The boom in new discoveries in Metallurgy gave way to a boom in industrialization, thus it will remain an important branch of engineering and science. People will always use metals and non-metals for numerous purposes. Guess what? In future, there would be robots extracting precious metals on other planets.
4. Imagine the world without iron, steel, copper, gold, etc. This is your answer.
Technology of extraction, purification may change but the need of this field will always remain.
5. Materials Science is the branch of future, whether it's nanotechnology or polymers or composite materials. These materials will form the base of engineering in coming future.

MTech Cryptography is a brand new course which ISI introduced this year. There is a new centre opened at ISI called RC Bose Institute of Cryptography which will be running this particular course at ISI. But in the subsequent years this course will be highly demanding.
May be the admission in these years will be easy but I can assure you if you can successfully complete the course with decent marks, you will surely be getting a job of an average lpa of 15 lakh and as well as PhD in Indian Institutes as well as universities in the USA.
RC Bose faculties at ISI have good connections in abroad so placements and PhD options wont be a problem in my view.

Here are the following options:
1. You can go for further studies i.e. Ph.D which is now of 3 years only (in most of the colleges).
2. You can go for the teaching job. You can go in many colleges and become the assistant professor or you can get the teaching job and can continue your Ph.D within the college only. This is the most efficient option because in this you can continue your studies while working.
3. You can join government sector organisations like ISRO, DRDO, etc. These are the big government organisations. You have a benefit that you can fill the form for both vacancies (B.Tech students and M.Tech students).
4. The last option is that you can go for MNCs. Here you can have many options too. You can also go in the IT sector. In IT companies, there is a need for electronics engineers. For more job offers or vacancies, you can check naukri.com or sarkarinaukri.com.
