I have been working at US Census Bureau full-time (Less than a year)
Great environment, fun, people are friendly, lot of work, and good ability to grow
Government Agency, so communication can be an issue at times.
I applied in-person. The process took 1 day. I interviewed at US Census Bureau in June 2009.
Scheduler was clueless. But interviewer was quite nice. Scripted interview with point system. Office was fine but interestingly it wasn't identified in the lobby. Someone told me they wanted to be hidden from the public. I met one guy who was definately entrepreneurial. Friendly office environment. The application process is definitely bureaucratic ... make sure you watch every step ... it's all about the points
