B.Tech Scope

Hi,
In terms of requirement of engineers - industry requires them in two levels. In junior level, they recruit Diploma engineer and B.Tech/ BE for senior levels. As you are in the mind set of job, your B.Tech degree is strong enough to fetch you a job in equivalent level.

Yes, it is. More specifically, depending on what is your trade and how skillful and good you are in your trade.

Hi,
Any newly introduced course has its own challenges. So, before you take admission, you must understand the course structure and the jobs you will get after completing it. This is a technical degree, which may expand to finding or designing solutions in agri sector using technology.
If you are innovative enough, then the course can place you well. The admission is through JEE exam.

To get a job in England is quite difficult for an Indian student as the work permit norms are very stringent. You should focus on getting a good job in a top IT company in India, and then going on-site to Europe/ US.

B.Tech in mechatronics can get below mentioned designations:
1. Robotics technicians.
2. Robotics test engineers.
3. Robotics systems engineer.
4. Robotics specialists.
5. Analyst researchers.

Hi,
CAT, MAT and XAT, etc. are for India. Whereas, GRE is for Master's degree in abroad. GMAT is for management courses abroad and TOEFL/ IELTS are English proficiency tests for all courses abroad. So, you can choose accordingly and research a bit more about it through the official websites.

Probably computer science.
While it might vary a little from department to department, learning CS will give you a good foundation for a career in animation (which is pretty much your only option if you want to make a career in animation).
I would bet that you will be able to take many animation courses for CS electives, thus getting the best of both worlds (getting a good foundation through CS, following your interests and expanding your potential are the ways to get employed in animation).

Yes, you can. You need to qualify a national level management entrance exam to get admission in a reputed B-school for MBA in marketing.

ME, M.Tech, MBA and PG diploma are some of the courses you can opt for. ME, M.Tech if you want to continue in the technical line, otherwise, MBA or PG Diploma for managerial roles and work.

B.Tech has better opportunities. You can see the development going on in the field of science. Technology is taking rapid strides and world is changing quickly. Engineering opens a vast number of opportunities for students. Students can opt from computers to agriculture.
India being a developing nation and it has number of opportunities in IT industries and other service sectors. 60% of India still dependent on agricultural products and farming. Hence, there are lot of opportunities in that sector too.
