I am a current student in Ross. I don't know CMU situation, but what I know regarding internship recruiting for Chinese students here in Ross is that 100% had received offeres, which ranges from Banking, Consulting to Marketing and Corporate Strategy. FYI, I also got offers from both CMU with some $ and Ross last year. No regret choice for me to come to Ross.
As for OCD, it is useful, however,don't count too much on it!! Actually, individual abilities and capabilities are of much more importance for recruiting! Both CMU and Ross provide a decent stage, it is you that deliver a SUCCESSFUL performance. By the way, somebody mentioned that Amazon hires a lot in CMU, but please ask them what is the percentage of Product/Marketing Management offers, which are far more difficult to get than Operation/SCM offers. As a matter of fact, according to Amazon recruiter, they hired the most students from Ross last year.
Good luck to you and we look forward to your joining as a Rosser!! By the way, MAP project of Ross rocks!! I am now in seattle for my last term of year 1.
