> Maybe you can come up with a better "test center" (perhaps a van?) but most people don't care at all about what ProctorU does with their computer.
Most people might not, but I suspect many of the best people for many tech, especially -- but also many other knowledge work jobs -- do care, quite intensely.
I don't know whether I qualify as "best in tech", but: last year I was approached by a large company which uses Django, and which solicited me to apply specifically because they wanted a Django committer on staff. In other words, I was absolutely a known quantity for them.
They still shoved me in their Fizzbuzz phone-screen funnel. Spoiler: for that, among other reasons, I stopped trying to follow up with them.
This does not seem to be an unusual practice for large companies. Even when they're recruiting specific people who they know and initiate the contact with, they still set these awful "prove you're not one of the impostor rabble we say are beating down our doors" hoops for people to jump through.
