I had two phone interviews and two WebEx interviews throughout the process. My first phone interview took about 20 minutes and it was with an HR Representative. My second interview was with the Supervisor. That took about 30 minutes and it was over the phone. My next interview was with the Supervisor again, but it was over WebEx. My final interview was in the office with an HR Supervisor, but due to a scheduling issue with that person, it was not face-to-face, but also over WebEx.
