Fannie Mae as Hogwarts

The main FNMA HQ has about 1.5 million square feet of office space.

That is roughly equivalent to 40 floors of World Trade Center.

Along with the sheer size of the office, each of the 4 floors is laid out differently: what is an open hallway on of floor is walled off on another. This makes it incredibly confusing if you are, say, new to the company. During the first few days I couldn't find my way out of the building.
