If you want to make money off of being better at hiring than Google et al you need two things: 1) the product idea for something to build that you can sell profitably 2) the hiring skill Neither of those are trivial to develop. I do tend the think the second isn't that hard to develop for specific situations (FAANG interviews are really aimed at hiring people who they could swap around to large different sorts of teams or roles and get along with, and be productive with, a huge swath of the company, though IME in practice that doesn't happen terribly often these days). But if you're doing it for someone else's company, your upside is capped by the upside of the company you're working for. And your reward is too - you're not going to command 10x the pay from a CEO you report to who doesn't themselves understand the difficulty of the hiring you're doing compared to "just copy Google" (or why they wouldn't have good results with the latter).
