One of the biggest drawbacks of working at Fannie Mae was its very hierarchal, top-down structure, especially from headquarters in Washington D.C. to the regional offices to the various offices located in each state. Oftentimes not all of the info you hoped to hear you received because it had to go through so many filters. Also, people who showed the drive, talent and abilities to succeed in a higher position I thought often weren't considered or even invited to apply. In instances where I saw this happen it usually was because they were seen as most helpful in their current position vs moving on to another position they want. Lastly, because of all the issues and turbulence Fannie Mae, along with Freddie Mac, went through because of its accounting scandal, the employee morale began to slip terribly.
