Does MBB care where a prospective consultant attended undergraduate if the applicant has a prestigious graduate degree?
For example, someone has an associates degree from a community college, and a bachelor's degree from a lower-ranking university (not top-25); however, has either an MBA or Ph.D. from a prestigious school (top 10).
No, not really.
It doesn't even need to be an MBA. I know a guy who went to a pretty low ranked public school (but obviously was one of top students there), is now at a Top 5 University for a Master's, and is going to enter MBB as a first-year analyst. It's actually pretty common non-target undergrad -> target grad -> MBB.
Nobody cares about your undergrad once you go to a top grad school, unless they went to the same school.
Very few people care where you went to grad school after two years post-MBA, unless they went to the same school.
Nobody cares about your undergraduate grades once you go to a top grad school. Absolutely no one. I chuckled when I read this.
Nobody cares about your grad school grades once you have your first job post grad school.
There is big network value to going to brand name schools, and it can help push you through a resume screen, but it's experience, success, maybe soft skills and culture fit that get people jobs and promotions after a few years of work experience.
