The point of concern here is your branch preference.

• For CSE it completely depends on your skill. If you are skilled enough, you are good to go off-campus. There are a lot of opportunities. You do not have to bother about on-campus placements.
• For ECE campus matters. There are a few core companies in ECE and they visit IITs only. Chances are low getting in core with off-campus too. So, ECE students either do coding or go for M-Tech or join small core companies offering low packages. Once you are good with Softwares/ Basics you are as good as a CSE graduate.

However, MAIT is more reputed than the remaining colleges. Here is a brief highlight of the recent placement statistics for MAIT.

Hope this helps.
