I know a few things about LNMIIT since I have few friends there. It is a public-private non-profitable college, located in Rajasthan. From what I heard from my friends, I will not recommend choosing this institute. 

• The main problem of this institute is the administration. There have been many misconducts by the management, in recent years.
• Scoring marks in college is very hard as the teachers usually give D and F grades to their students which makes their GPA < 6 and hence making it difficult for them to sit in the placements.
• There is nothing like supplementary exams which is common practice in IITs and NITs.

If you want to build upon your career, don’t choose LNMIIT. Mostly, half of the batch fails in the exams.

Finally, life is tough at LNMIIT, so don’t go for it. Look for other options.
