Engineering in India

Whatever weapons industry India has is in the hands of the public sector. You have the gun factories, ordinance and armament factories, all under the ministry of Science and tech or defense. These organisations have their own independent recruitment process. DRDO is an organisation that works in the field of development of weapon systems. It has undertaken development of many useful technologies associated with warfare. Weapon systems require engineers from all streams including avionics and aerospace. NAL is another organisation that contributes to weapon engineering. HAL is one of the premier avionics and aircraft manufacturing outfit taht is deep into weapon systems. There are many PSUs involved in ship building in Kochi, Karwar, Kolkata and other places which involve state of art weapon systems. Most of these defense related organizations recruit standard run-of-the-mill engineers from electrical, mechanical, computer, telecom, production streams ( the list is not exhaustive. They often have vacancies for general graduate trainees as well as Scientist / Engineer posts) through their own recruitment process. No they do not do campus because that would be unfair to other institutions I guess. However ISRO provides special B.Tech / M.Tech / Combined courses in Avionics and aerospace. Absorption isn't guaranteed. But graduating from that course gives you a head start for weapon engineering not only in India but abroad too.

B.Sc in life sciences:
This degree is a good undergraduate degree but not favored by most of the people due to the limited opportunities available to the students after finishing their degree. I have a lot many friends who have done B.Sc in biotechnology and other courses like B.Sc in biology, zoology, biochemistry, botany and many more. All of them have to go for Masters in life sciences and then further Ph.D. and furthermore, the population of students who are doing life sciences courses is increasing because most students are not able to get MBBS, BDS, BPT, BOT and other clinical courses.
Thus there are lots of unemployed graduates with life science degree, they are resorting to school teaching jobs and clerical jobs but now those fields have also reached saturation. What are the few advantages? Students who are inclined towards the Biology courses are more comfortable as they are learning what they like. They tend to do these courses and side by side after that prepare for MBA as they know that they don't have many job opportunities just with B.Sc. As you told that you have got a good college for B.Sc. Then you can get that good tag name with you while preparing for other exams for management, or UGC NET. If you are good in studies and get good guidance then you will be able to get top notch universities abroad as well. Now I will tell about my field of specialisation that is biomedical engineering.
Biomedical engineering: This field is related to the application of all fields of engineering in Healthcare. I have seen that students who don't get admission in the medical fields are more interested in human physiology and human anatomy, which has driven their interests towards the medical field. Biomedical Engineering gives you a chance to drive a technical solution faced by the humans in their physiological processes. And you will be working related to human body
Biomedical Engineering as an undergraduate discipline in any of the IITs and only IIT Madras offers a B.Tech in Engineering Design with M.Tech in Biomedical engineering. Biomedical engineering is in two NIT's. So all the undergraduate colleges in biomedical are at the same level. It will depend on the way you study Biomedical Engineering will determine how you will do in this field.

Before answering this question let me share one important information. In general, metallurgist deals with metals from earth mining, processing, smelting, making the final product, etc. Who is a billionaire Indian in the field of metals? Mr Anil Agarwal, the owner of Vedanta. Dealing in all ferrous, non-ferrous metals and oil. No doubt, by his vision he is going to be number one, in metal in coming few years. So, you can think of the scope in India and outside. Major players are Vedanta/ SAIL/Hindalco/ Hindustan copper / Jindal/Bhushan/ Birla / Hind Zinc/ Strelite /DRDO/ ISRO / Car and vehicles industries/corrosion field in acid and chemicals plants and many medium industries apart from these. In fact, if you really goes for industries contribution in India GDP, metal industries comes on number 2. So, friend, the scope of metallurgical engineering in India is still not fully explored up to its potential.
