Hello Jeevan,
If you want to be placed in a good company after an M.Tech you can choose old NITs specifically NIT Trichy, NIT Warangal or NIT Suratkal.
But if you are interested in research, you can choose new IITs. IIT tag may help you in getting a PhD from a good university. And for IIT Tirupati, since it is a new IIT and M.Tech batches have started just last year nothing can be said about its placements. Depending on the cutoff scores you can choose whether go to for spot rounds in other IITs or go with IIT Tirupathi. New IITs are developing at a fast rate. The infrastructure in IIT Tirupati is still in developing stage whereas the academic structure here is very good and the professors here are also highly qualified. But you should be ready to put in efforts by yourself too.
If you are interested in doing a PhD after M.Tech, then NIT Rourkela would be a very good place. If you do good research during M.Tech and publish your research as a journal paper, there is a good chance of doing a PhD in prestigious IITs like Bombay, Chennai, etc. Professors here have good knowledge and experience and infrastructure is quite developed along with good lab facilities.
If you are interested in campus placements after M.tech then Computer Science department people are luckier in that case. But in other departments, placements are not that good for M.tech students. Still, a few specialisations here can give you better placements if you work hard during your course curriculum. And if you are planning to prepare for competitive examinations along with your M.tech, you will get ample time to prepare but it needs good planning and time management.
A decision regarding any technical institutions should be made keeping in mind better infrastructure and facilities available. NITs have stronger alumni network as compared to the newer IITs. But IITs are better in themselves. So decide as per your interests and convenience.
Hope it helps!
