My husband is in a position to interview and make hiring recommendations for IT here in NC and he has said it doesn’t matter. He looks at the person’s qualifications way before he looks at where they went to college.
Of the friends I have who are at the upper echelons of their fields, I don’t think it matters that much where you go to undergrad either. I think you can definitely make connections in the Ivy League and elsewhere, but you can also do that in grad school and probably make better connections there.
I’m in Chapel Hill, so not a fan of Duke 
. Just do not like that place!
