What? So companies cant hire whoever they want in whatever way they want? They all have to have a set process open to everyone?

I've hired people before on the spot because of who they are and what they know. Is that somehow wrong?

Life isn't fair and sometimes the right team is who they already know. Do you want them to interview every robotics researcher on the planet in a massive interview round instead of getting work done with a pretty great group that's already proven themselves?
