Sounds great, but I'm not sure this will work well for individual contributors. Say the company is small, with a small team. Can you afford the amount of time it will take to find this bespoke unicorn engineer? Say the company is large, with a large team. Is this process going to scale to bring in, say, 50 new engineers?

Maybe it works better with management tiers where their impact is more indirect, and there are fewer of them, which mitigates the problems.

If I have a team in pain and we need more people on it, or different people, I don't know if I can wait six months for the one person I want to hire to become available and willing. Sometimes, you gotta go with who is available.
