I spoke with a recruiter on the phone, and then I was invited to interview at the office. The interview was conducted by three supervisors which was different than other interviews I have attended for accounting and auditing positions.

Applied online. schedules phone interview with the HR. Phone interviewed with supervisors and managers. Typical interview questions, not too difficult. Be familiar with your resume and tell a good story about what you did for each position. There will be a writing test after the interview. It is about audit concepts and government audit. Not too hard if you took audit class before. BTW. they provide a few pages of PDF file about government audit. All the answers are there. Don't panic.
