I have to pipe up on that "first guy" bit. As I've said before, I'm often the first guy to talk to the new hire. I'm not desperate for friends or looking for an ally. I'm being paid to bring junior members up to speed quickly ;-)
And in the same meditation, the second point is communication: I'm looking to feel out the new guy to see how well he will perform (the first point in that meditation), to see how willing he is to get help when he needs it, without overburdening his reporting structure.
(And the only reason I keep using "he" here is because our new student is a male - I used the same strategy when bringing women on board as men.)
