I have been working at U.S. General Services Administration full-time
GSA has good morale and support.
Nothing from my experience is negative.
I applied through an employee referral. The process took 3+ months. I interviewed at U.S. General Services Administration.
Was an informal process to start - meeting the hiring manager and then their supervisor as well. After the hiring decision was made things took a little time to process with HR. They kept in touch and explained what was happening but it took a few weeks before I could get in to start working.
