Electrical and Electronics Engineering

The rank is not sufficient to get CSE, however there are slim chances for ECE/EEE in 3-5th round in lower ranking NITs.

Money is a secondary factor, not a primary one and if money is such a big deal for you then why did you opt for science stream in the first place? According to me, with that type of mindset, you may get a high package, but there will be a time when you will be unsatisfied with your job because you were in it for money, not because of your interest.
You can make a good amount of money in other fields too.

Hello Ghali,
Your rank is far beyond to get any branch in any of the campuses of VIT.

Yes, you can get into SASTRA in atleast one of the three streams mentioned above. As you would have known already there are 2 steams for admission in Sastra. If you have a JEE score of above 150 then you can enter through stream 1. With your board marks alone you can enter through steam 2.

That's good but you have to go on another Application of https://Shiksha.com, that is, Naukri.com where you find job details and job in various company.

Hello, by this rank you got mechanical engineering in SRM University main campus as VIT takes students who scored less than 20k. SRM is also deemed university so you may go here.

Hi,
I will advice you to refer to the Skilled Occupation List of these countries to know professions in demand. You will get a clearer picture of the market requirements. It is available on the Internet.
