I have to say this is how I've always interviewed people - I tend to be optimistic and assume people don't lie about their skills and experiences. So when I've been asked to interview people I mostly want to talk about projects, hobbies, and general things about developing, debugging, and the process by which people solve problems.

I don't want to know if you can do specific things, if you can't you'll learn, but I do want to know if I'm gonna find it easy to get along with you, if you seem like an interesting person, and if I can stand being in a small room with you for 7 hours a day.

I suspect this is just another kind of bias, but I've had good results.
