Rutgers Mech grad here working in the industry. For the most part locally NJIT, Rutgers, and Stevens are respected about the same. Alums from all schools are renowned and hired.
Rutgers is popular more nationally. Stevens and NJIT are smaller schools and smaller campuses.
Rutgers offers the better experience overall as the New Brunswick campus is huge. Dont like being around the science geeks all the time on Busch? Head on over to college ave!
Its just over all a more diverse experienc (more majors, more students, more things to do, more options, more athletics)
Every alum I know from NJIT was a commuter.
From what I have heard professors at NJIT might be at the bottom. Every alum ive came across complained about them. Don't hear that from the Stevens crowd.
I personally enojoyed the professors at Rutgers. Yeah there were one or two bad apples but most students are made aware of which ones to avoid by word of mouth.
