New York Life interview questions

Several months after applying, I heard back from New York Life about this position, and was scheduled for an interview at their Cleveland Service Center, where I met briefly with the human resources representative. She let me know I would be speaking with two of the call center managers. I then went into one of the conference rooms and spoke with them. We had about an hour long interview, they both took turns asking questions, and then they sort of surprised me by saying I would then be speaking with their supervisor. I went to her office and spoke with her for about an hour, and two and a half hours after I came, I was finished. They were all quite nice, but it was very formal. About a week later I received my offer over the phone, and was told I wouldn't receive anything in writing until I accepted, which I thought was just a bit odd, but I asked a lot of questions and took a few days to consider it. After I accepted the position, I received my formal offer letter and information on benefits.
