I was contacted via phone about a month and a half after sending my application materials. Unable to reach me initially, they left a message offering to discuss the position with me and instructing me to call back before the end of the following day due to a tight time frame they were working on. I called back the following day, was given a brief description of the position, and scheduled an in-person interview for the following week. I was also informed that I should expect the whole interview process to last about 2.5 hours.
The interview itself started off with a tour of the building before settling in an interview room, where I provided my identification/citizenship documents (driver's license, passport, Social Security card, Birth Certificate, Selective Service Registration card, resume, transcript, and contact information for references). I was asked to fill out a questionnaire with some common interview questions ("What are your strengths/weaknesses?") and some specific to this position ("Would you be willing to train in a classroom setting for approximately 8 months before starting?" Then a second interviewer came in to ask verbally a few more common behavioral questions ("Describe a time when...How did you deal?"). I then met and talked with someone currently in the position I was interviewing for to get a perspective on what I'd be doing. Some last follow-up questions about the logistics of starting if/when I was offered the position and I was fingerprinted, then excused and told to expect a phone call.
Two weeks later I was contacted via phone (did not reach me) and then via email to be offered the position.
