The most reliable rankings that are the most "normal" are the US News ones, so I would not get distracted with Forbes or others more exotic....
https://gmatclub.com/forum/mba-rankings ... 99812.htmlStern is currently ranked as #12 and it's 5-year rank average is 14
Johnson is ranked #15 and it's average is 15
What Johnson has going for it is Ivy League and new Tech MBA they launched. That gives them momentum though remains to be seen what that actually amounts to. Stern is in the New York City and has access to a great job market right there.
Tech PM roles will require quite a bit of networking and I am going to guess that both Stern and Johnson will give you similar access to recruiting opportunities and consideration when evaluated for roles. I would guess Stern's larger class size and being in the city provides more on-campus interactions, coffee chats, and recruiter interaction than being in Ithaca.
P.S. I would talk to the current Stern students and Johnson - I am sure both are very approachable about what opportunities exist. Both will probably try to play up what's happening but you can get a good sense about what jobs and internships are being considered. This is a good time since the holidays just started. Students should have plenty of time :_
Congratulations!
