Name of school matters for an undergraduate degree in the sense that some schools draw a lot of recruiters onto campus, and some don’t. If you are at a school that doesn’t draw a lot of recruiters, the search for employment will be more burdensome.
The Big Ten schools all attract enormous quantities of recruiters from quality companies. There have been studies concluding that many employers prefer graduates from large, public flagships to graduates from smaller, “elite” privates. Something about surviving the large school process vs perceived handholding.
IU will provide good opportunities, and particularly graduates of its highly touted business program. Fingers crossed that your S gets into it.
