After even 2 years post-graduation those grades will only be inspected for McKinsey/Bain/BCG consulting positions and maybe some corporate executive-track / future C-suite-potential type roles. Almost no one will ever use them for hiring decisions. But also curious how much of the grade inflation is driven by increasing selection bias. With the bar to get into top schools is raised higher and higher, maybe most of the students really are earning their inflated grades?
