FWIW, I’ve seen the same practice advised in “unconscious bias training”. The idea being that if you notice that someone went to the same university you did, or a prestigious university, or worked for a prestigious company or a company you worked for, you’ll be unconsciously biased in their favor. The antidote to unconscious bias is to have a standardized interview and a standardized rubric for evaluating the candidate’s answers and to disregard any other information.

I’m very deliberately not sharing my personal opinions on this.
