This is all generally very good advice but I’m equally amused at the ridiculous portrayal of “businessmen” throughout this post; most people do not see themselves this way and it’s sort of goofy to think they do. But that isn’t terribly important to the message.
Oh, and one other thing, if you’re at a 10-person ish startup, definitely don’t act like a company that is 1000ish. You’ll lose. And so your hiring practices should generally not align with what is outlined here.
