Applied via usajobs.gov with the typical questionnaire. I got two automated emails from the HR system and then a very nice email from the hiring manager. The manager interviewed one-on-one, plus he had one of his staff members present. The staffer was mostly disengaged and dead weight to the interview. The interveiw was conversational with a few particular questions of interest. They allowed time for me to ask all the questions I wanted. Answers and discussion seemed candid. Interview was 90 minutes. I felt very positive leaving the interview. Note: arrive early for airport style screening which does not move along very quickly!
