M.tech renewable Energy in JNTUK kakinada worth studying?

In JNTUK, there are no campus placements available for master’s degree holders. TCS sometimes visits for the interview of post-graduate students and only hires a few students depending on their performance in interviews. 

The course is not recognized by AICTE so you won't get many opportunities after completing your course and won't even get any stipend through your GATE qualification. 

It is better to prepare for IITs or IISC if you want a career in this field, as these institutes will help you a lot to achieve your goal. Also, a post-graduation from an IIT or IISC will add a boost to your career. It will also be very easy for you to opt for research internships or a Ph.D. if you are planning to do in the future. 

It will be better to avoid this college and rather prepare for some better colleges such as IIT or IISC because there are no campus placements available here and neither you will get any kind of opportunities or exposure studying in JNTUK.
