Some of this might depend on where you are interviewing, but it will always be a standard set of questions at the initial interview stage. This interview is typically with management staff from the offices that have the vacancy, but not always. If you are a qualified, desirable canidate, then you will be called back for a abackground investigation. Typically there are more applicants than come back for abackground intervew than vacancy's, so it doesn't necessarily mean you have the job at that stage of the process. The background investigation takes 3-4 weeks and consists of a history of your work, work ethic, personal experiences that would prepare you for the job, education review, ect. Once the results of those investigations are in, you will recieve a phone call or a letter advising you of the status. I would bring your resume and supporting references to our initial interview, and then back again at the background stage. Hope this helps
