CSE at NMAMIT is really good option as I studied in NMAMIT, I can confirm this, but the problem is the college is situated in a very rural area and opportunities for easy Internship are less. NMAMIT has good startups and research centres but no great company collaboration. Placements are good for CSE in NMAMIT.
MS Ramaiah is the best Engineering college in Karnataka no doubt and as it is situated in Bangalore City it provides opportunities for easy Internship for students. Placements are best in MS Ramaiah as compared to NMAMIT. I am not sure about the branch (Industrial Engineering and Management) and its scope. I overall I would recommend MS Ramaiah over NMAMIT.
