I completely agree, and I think this is the natural evolution of Amazon (and, to an extent, corporate America). Amazon gets to treat their min wage warehouse employees as fungible, and their process around hiring and firing shows that. Have they gotten to the point where a certain amount of their engineering resources are the same? It's looking like they are trying to get there.
It's a demonstration of our privilege on HN that we rally against these interviewing practices, yet they are a mainstay for a huge percentage of the USA.
I'm not sure I'm getting my point across well, but I think there's going to be a point where this becomes more and more normal across more and more companies. They'll hire people to abstract the very difficult parts of computers away, and bring people in en-masse to fill in the blanks.
