Electronics and Communication Engineering

Hello Krishna,
As per your rank in JEE, you must switch it to any NITs or BIT Mesra, however BIT Sindri is also a reputed institute but it lags in giving a good environment, exposure and good placements.

Yes, you can get a job in ISRO after completing B.Tech in ECE but the vacancies for ECE is very less every year and the entrance exam of ISRO is also tough. You have to work hard to get a job in ISRO.

I think you won't get NIT, Warangal. Since, your rank is around 12500. You can get chemical engineering in Warangal. In my opinion, you should get admission in Warangal. It is very old and reputed NIT in India.
All the best.

This decade belongs to electronics. Electronics is and will continue to impact all walk of life. Computer is the facilitating technology for all business and personal activities. Indian IT industry has started showing sign of decline. Also, ECE engineer can work in IT companies. Therefore, electronics will continue to best career option in the field of engineering.

It is a good university for EC.

Hi Vibhor, you can get the main campus of SRM university but it is not possible to get ECE there with a rank of 30397 but in all other campuses you can easily get ECE with your rank.
You can use the rank predictors to know a list of courses that you can get.
