It’s not a reference check to see “is sam0x17 a good dev?” at the end of a hiring pipeline, but rather “I’ve got an open role and remember that sam0x17 is one of the best devs I’ve ever worked with; let’s get them into the company!”

That might have been feasible pre 2020. But once I started working remotely and looking for jobs outside of the metro area where I spent most of my career, the usefulness of my network dropped dramatically.

You would see the same from someone early career. Their skills would progress so fast it would be crazy to ask someone for a reference who worked with them when they were 22-24 and now they are 27-30.
