I don't see the issue. Why change a formula that is known to work? How is anyone to know if it's an honest description and their attitude is genuine? That's what reputation is for. Reputation is most valuable in my opinion and that goes for both potential employer and employee. If it's not available proxies may give some indication, or character evaluation by in person meeting. Does the pitch align with how the other side comes across? It's not a 100% guarantee. The rest is risk, which we can't be without.
