Internship at LNMIIT is good enough but if you can get an internship at reputed IITs or BITS, Pilani, then you should prefer them.

LNMIIT is much better than VIT in terms of CSE in terms of placement and faculty. There are basically two organisations- ACM and CSI which help for their development. In CSE, this year, the highest package is 29.2 LPA.

Basically, mechanical is a good branch in LNMIIT and you get the best knowledge about this but in case of placement, it is not good yet. In the previous batch approximately 5 to 10 student were placed but in case you are planning for higher studies like MS, MBA or any other thing then LNMIIT is the best place because of their environment and senior junior,senior faculty interaction and also there are two prestigious organization ASME and SAE make you get more knowledgeable.

Hey buddy,
You have not scored good marks to get an NIT. You can try for your state government engineering colleges.
