English,
Did you already have the CE525 type rating when you interviewed? That may have been the difference. Since they operate 525's, they know about them, and that could have swayed the way you, in particular, were interviewed. They did ask most people to discuss a particular system, any system, from any aircraft that you had previously flown, in any former lifetime. My interview took a slightly different venue that really didn't mirror any other that I spoke to. Also, I did not know anybody there when I applied and interviewed.
