Notified by "Staffing" of selection for an interview, who I would be interviewing with (multiple people, but no clarification regarding one or multiple opportunities; interview or interview(s), and date and time were set. Ironically, my last name and that of one of the interviewers was the same, prompting an additional phone call from an "HR" for clarification, and further followed up by a "Conflict of Interest" questionnaire to ascertain previous Government affiliations. Directions from Staffing entered into GPS took me to the wrong entrance, delaying my arrival for the interview. (Huge campus, highly secured) I notified Staffing, was redirected to appropriate location, and interviewers had been notified. Arrived professionally prepared with comprehensive personnel packages for all interviewers identified. I felt the Interview went exceptionally well; mutually impressed.
