Juan -
My wife is a senior recruiter at the 'other' bank down the street from you. She tells me it makes absolutely no difference if you go to the same school for your MBA as you did for your undergrad. She also says that it doesn't matter where you go
near as much as people think it does (...as long as it is an established, respected, accredited school). And it is true, no one really cares what your GPA was.
The only thing she noted is that if you are applying for a job to a place that has a strong alumni from one school, then the school can give you a leg up on your competition. For example, there is a strong Florida State bias among the capital management group at the bank. Applying for a job in that group with a FSU MBA would give you an advantage obviously.
UNCC's MBA has a good reputation. Also, you probably are aware that Wake Forest has an MBA program that has evening classes in Charlotte. That would be awesome on your resume'.
Just another 2 cents for you to consider. Good luck in your continued search.
