Intensely political; managers are distracted from the essential work of managing by political considerations, "Managing upward" is the key to career success - lot's of attitude without credible results. Bad decisions are made regularly because short-term thinking dominates. A very strongly hierarchical culture - that is too big for hierarchies to be effective. Lot's of teams going nowhere: not cut, not funded for success - career deadzones. Deadening series of meetings: coordination is necessary, but heaven forbid there a technology to cut away the endless meetings that sap productivity. Poisonous managers, as probably has to be expected in a culture that has so many, but offers no training, except for how to avoid lawsuits.

Even if you think you are meeting your objectives/committments, you're not. There are so many 'unwritten' factors in how management judges you, and these factors can change every month without you even being informed. Watch out for your peers who will back-stab you every chance they get in order to get a 2-3% annual raise. Expect to have a new manager at least 2 times per year.
