The entire process was trivial. Required no preparation. Went into an interview and the interviewer asked me a bunch of questions that had nothing to do with the job itself. I was given the offer as I walked out.

I interviewed at a job fair. The woman who interviewed me was very nice. We had an actual conversation while also getting the interview completed. (Side note: It seemed like she was grading my answers to her questions as red, yellow, or green.) I got a call two weeks after the interview to schedule a drug test, but I missed the call because I was on vacation. I called back a week later and they were very understanding. I had to take a drug test (this gross swab thing that looked kind of like a pregnancy test that you had to swirl around in your mouth). I also had to do a background check.
