I am an ECE pass out from batch of 2022 from The LNMIIT.
From what I have observed & heard from my CSE branch friends I would say The LNMIIT is much better than many NIT’s for pursuing Computer Science. The CSE faculty is exceptionally well in teaching and are friendly.
The placement record for session 2016–17 for CSE is also commendable. Companies like Amazon, Microsoft, Samsung, Kayako, DirectI etc. visited campus for on campus placement in session 2016–17.
If you have an interest in Computer Science then I would suggest “The LNMIIT” is the best place to get started with.
