I worked at National Transportation Safety Board as an intern (Less than a year)
Everyone was extremely friendly.
Location in DC was great, with nearby access to buses and trains.
All of the managers and higher ups were very approachable, friendly and knowledgeable.
As a government agency, a transit subsidy was provided for the day to day commute.
Working details out with HR was a bit difficult at times.
It took awhile for documents to go in and be signed (but hey, it's the government) for interns to be approved to start working and so forth.
Advice to Management
Perhaps work more with HR in regards to onboarding, at least for interns. Also, try to get move involved with the Pathways program and working with all of the interns.
I applied in-person. The process took 9+ months. I interviewed at National Transportation Safety Board (Anchorage, AK) in August 2014.
This was heavy in the USA Jobs application process. Had to fill out the USA Jobs application, supply a federal resume through that system, but then answer the NTSB specific questions and KSA's as well. VERY intensive, also had to supply supporting documents for required qualifications. The screening and federal jobs oversight of the entire process at the Washington DC HR office was the absolute worst. Now, one year after submitting the application, they still have not done anything with the actual USA Jobs application, and took everything closed-doors to hire someone under the table, against federal hiring procedures.
