I was contacted by an HR representative to set up an interview time. At the interview I met with two managers for about 40 minutes and then had to do a mock phone call. The people were very nice and I was able to ask questions and shadow another employee for about 20 minutes, getting a better feel for what they do on a day to day basis. I didn't end up getting the job, but overall it was a good experience. No outlandish or particularly difficult questions.
