I'm a current undergraduate at Tepper and spend a lot of time in the building. By rankings, Tepper's graduate specialties are still primarily Supply Chain and Manufacturing related disciplines. For an idea of how many MBAs end up going into each industry, check out this link from their official website (I can't post directly because of membership restrictions): tepper.cmu.edu/corporations-and-recruiters/recruiters/salary-statistics/mba-statistics/2010-mba-graduates-compensation-by-industry/index.aspx
I do think that the students are of a high caliber and are definitely capable of networking and getting into banking, but one of the chief complaints is often that the location (Pittsburgh) is an annoyance when trying to reach and visit NYC-based firms. S&T looks for people who can think on their feet and are very good with numbers, so IMO if you can land a first round interview, if you're that good then the b-school name/prestige/type of degree you have matters less.
