<p>Some CC members have put out lists of what top consulting/business firms consider as "core schools" and Northwestern appears more often than Emory. So that sorta answers your question about job placement. As far as the undergrad business ranking goes, keep in mind many prestigious biz schools don't have undergrad programs. This makes the prestige for undergrad programs very top-heavy; you have a few (Stern/Wharton/Ross/Berkeley) at the top and after that, it's a significant drop and just "everybody else".</p>
