PSGCT Coimbatore

Future scope in this branch or any other branch depends upon how and what you see in that branch.
I am also pursuing metallurgical engineering, and can tell you what I feel about metallurgy.
Well, broadly you can divide this branch in two broad categories:
1. Research
2 Industry
Areas where research is going on in this field are smart materials, sensors, Nano materials and various other areas. And, jobs in this sector mainly include in research institutes and many R&D section of companies like Intel and many more. And, also huge amount of research is done in this field in other countries also (Dakota School of Mines in USA)
There are various types of industries
1 Nonferrous extraction: - VEDANTA, HINDUSTAN ZINC LIMITED, SESA STERALITE, RIO TINTO.
2. Steel plants:-JINDAL STEEL, TATA STEEL
3. Foundries (this is basically a casting industry where gear box housing and various other type of castings are there, which are made in foundries):-MAHINDRA, SWARAJ, TATA MOTORS.
Pay package depend upon various factors, like which company, what position you hold there etc.
It is also true that mostly (not all cases) working conditions are bit tough, as dust, high temperature is there. But, not all the time. One need to be there in such environment.

Dear Rishab,
Try for some good private university. Many reputed private universities are offering B.Tech CSE. They have their different criteria for admissions. Some offer admission on basis of JEE scores, some offer admission on basis of their own tests and some offer admission on the basis of both. Some even offer direct admission on basis of class 12 marks. Some of the universities also offer scholarships on basis of your performance in class 12 or JEE or their own test. You can check the details of any of the reputed universities like VIT, Lovely, SRM, etc. All these universities have wonderful infrastructure and world-class facilities to offer to students apart from good placements.
Good luck.
