I have been working at Office of Management and Budget full-time (More than a year)
In the thick of policy in Washington DC. You learn a lot and quite quickly. They expect you to be smart and intelligent and to be able to solve a myriad of problems. Though, my division allows a good full year of "training" so I felt absolutely prepared. Dealing with individuals from the Domestic Policy Council, National Security Council, and at the Secretary level throughout the Administration, a really great job indeed.
There are some long days, especially during budget season (September - February). But if you have a good and understanding boss, you shouldn't have problems.
I applied through a recruiter. The process took 5 days. I interviewed at Office of Management and Budget (Washington, DC).
I declined to go to second interview--accepted another job. But interviewers wanted to know how my former experienced would fit at OMB. 3 interviewers-all women, white. I noticed that this place is NOT MULTICULTURALAT ALL! EXTREMELY low proportion of Blacks & Hispanics,high majority white women and men--odd considering this office should be a leader in representing the cultural diversity of U.S. agencies.
