Just had a thought with my evening reading:

s://.gibsondunn.com/lawyer/doran-kenneth-m/ - Gibson Dunn's Managing Partner: University of Southern California

s://.lawgazette.co.uk/people/wills-power/5070538.article - Freshfields London Regional Managing Partner - University of Liverpool

s://.linklaters.com/en/find-a-lawyer/aedamar-comiskey - Linklaters future Senior Partner - University College Dublin

Maybe HR is snobbish about universities as a way to sift CVs but they're not at all related to work once you start practising...
