I hope this is in the right forum, if not I do apologize.
I have heard that getting your undergrad and your MBA at the same school is looked down upon. Infact my uncle did it (decades ago) and the companies he's worked for weren't enthusiastic about it (FYI he's not in the business field.) On the other hand I have actually had several professors who got their undergrad and MBA at the same school and acquired there PhD elsewhere, and even one who obtained all 3 from the same school. So is it acceptable to get both from the same school, or does there need to be a change?
