A high energy political environment. If you just do your work sincerely, but don’t keep your eyes & ears open (for what’s going around you) or if you don't know people (Director level and above), it is very hard to survive.
Re-org is part of their culture. Before you stabilize with one re-org, another re-org will happen. You need to quickly adopt & rapidly "jump ship" from one group to another, else you will have no future.
They have too many inefficiencies that they are struggling to improve in the eyes of FHFA (their monitoring / governing org). They pretend very well as though they are improving, but it is the "same old wine" in a new colored bottle.
You do not need to have special talent to get an "officer" position (Director & above) in this company. All that you need is "to stay in the good books" of some of the existing officers. That's all.
