If he treated it like a game that you win, he won, but he can't just go home now, he's signed up to be on call 24/7. I'm not wealthy but I've treated job interviews like this and been unhappy after "winning". Now I'm highly selective about what I do. Losing such personal freedom needs someone with a real conviction about the job and stamina, he may have it, otherwise he'll be miserable. The White House probably came across as a dump compared to what he's used to.
