I first learned about the job opening through Craigslist, and I felt that the posting was a little strange. The original posting gives no information about the company at all, which seemed a bit shady to me.
I received a phone call within the week from a woman with a very friendly voice. She told me that the company wanted me to come in for an interview at 10 am in a couple days.
At the interview I met with the receptionist, who was very friendly and funny. She told me what to do and eventually I was ushered into a room with 4 managers from various departments. For the majority of the interview (which lasted about 25 minutes) I was given an in depth description of the job's duties and at various points they asked me if I was ok with doing said responsibilities. Of course I said I was (I wouldn't have gone to the interview if I didn't feel like I was up to the job). At the end of the 25 minutes the group asked if I had any questions (honestly I felt like they had covered just about everything that was important so I could only think of a couple questions)
Overall I would say it wasn't bad, but I was surprised they didn't ask me any questions that you would expect from a normal interview.
