I think you've hit the nail on the head. I've been on both sides of the desk so many times. When I'm hiring, I'm trying so hard to recognize the person is nervous, probably interviewing at multiple places, and they don't want to be asked to solve stupid algorithmic puzzles that will never come up in their daily work. While interviewing, I try to recognize that they NEED to ascertain whether I can actually solve problems performantly and quickly. They also need to quickly decide if I'm worth the high dollars they're about to offer me. Because of this, I often hire people I've already worked with. I'm also often hired by people who've already worked with me. I hate that this leads to a very homogeneous experience... or even what might seem like gatekeeping. I've just found that the best indicator of how a person will perform, is already being familiar with their work.
