This is a well tread path, but I do believe that we’re you earned your degree matters. Take the LinkedIn thing - look at as many companies as you want. If where you earned your degree did not matter then you’ d see schools randomly listed. That’s not what you’ll see. LinkedIn is not definitive but it is indicative.
A single data point is just that, but my S is in an AI research group in a SV unicorn and everyone in the group (MS and Phd only) is from 3 schools : Stanford, CMU, and Cal.
