After doing some research online, I would suggest not to go for IEM at Ramaiah, until and unless you are extremely interested in studying that particular subject. Since it will not pay you anything and you will eventually wind up in the same category of mass placement at one of the service-based companies. 

Double-check the topics you will be studying. EEE is usually less exposed than IEM, yet EEE is regarded as the most complex branch to be studied. 

The majority of EEE / ECE / other branches receive job offers from Infosys, HCL, Accenture, or Tech Mahindra.

So, what is the point of learning core Electronics if all you have to do at the conclusion of your engineering degree is code? If you want to build a career, think seriously about the branch you select. Regardless of the institution you attend, I believe EEE is far superior to IEM. Pursue EEE only if you are truly passionate about the subject.

Instrumentation & Control Engineering and Electrical and Electronics Engineering are different branches. Although, both of these branches have some similarities. To choose between both of these is your choice.

Yes, Kongu Engineering College is best for EEE, and faculties are well stuffed to mentor throughout Engineering.

Most probably on the core side, you will be getting an opportunity for some good companies like Robert Bosch, Vedanta resources, Soliton solutions, and some small scale companies.

On the other hand, you will get opportunities from IT firms like Accenture, Zoho, Wipro, Infosys, Harman, Cognizant, etc. But keep in mind that if you are dreaming of joining a core company then you have to be very much strong in your EEE subjects both theoretically and practically.

One of my friends is an alumnus of Kongu Engineering College. In my friend’s batch, only 5 students got placed in core companies out of 100+ eligible students. Others including him got placed in the IT sector.

The better choice is undoubtedly EEE at BITS Goa than ECE at NIT Jalandhar.

NIT Jalandhar is still a developing institute whereas BITS Goa is a well-established institute that has got reputation all over the world. Most of the students have cracked competitive exams like GMAT, GRE, and UPSC, etc with a good rank.

You will interact with people who have appreciable knowledge and you will have healthy competition as BITS Goa don't have caste reservations.

Finally, if you can afford to join BITS then do it if not take a loan and don't worry about returns. You will get them in a year or maybe 2 years. Ultimately the choice is yours.
