Pretty simple for the most part. Got referred to an interview from Kelly and the interview itself was very straightforward and clear. They sent me the offer a week later

I was called by a staffing agency about the opportunity. They told me they would reimburse me for the trip if I flew out to interview. They also mentioned a sign-on bonus for relocation. I came in for a three-person interview. The director, and 2 managers. Questions were very basic and the process was relatively informal. They showed me around the facility and introduced me to a few of the workers.
