My first interview was in a small group setting where the manager reviewed the career, the company, and the expectations. It was a very informative session and provided me with answers to questions I didn't even know I had. After this session I received a call back a couple of days later to schedule a one on one interview. That interview lasted about 45 minutes. At the conclusion of that interview I was asked to provide an email to the hiring manager stating why I thought I was a good candidate for the position. I was called back a couple days later and offered a position.
