<p>I would say that your undergrad institution will indirectly effect your chances for admissions to a top MBA. The reason for this is because the quality of work experience is the biggest factor for MBA admissions, and attending a prestigious undergrad school opens door to IB and Consulting (the 2 feeder industries to top MBA programs). If, however, for some reason you are able to get a job in the above 2 professions from a non-target (really hard btw), and you perform well, then you undergrad school doesn’t really matter.</p>
