It depends. If you are well likable and in w/the clique than a few mess ups will not be a big deal. If for some reason you are not well liked or received you will never progress through the organization. It can be very political.
From within B-D HQ's very difficult to move up, across, or abroad. I got the impression they like to keep people pigenholed. As big as a company they are and with so many locations it is very difficult to transition from within HQ's.
Also @ B-D HQ's is not what you know, but who you know and how much you are liked. You have to fit the mold and also the "cliques" too. Otherwise you might as well be elsewhere.
