Oh, please. Perhaps they care about pedigree and GPA for new grads, but what else do they have to go on? I'm 40, and they didn't seem to care at all where I went to school nor what my grades were. The interview was challenging, but a lot of fun (the good kind of challenging), and certainly not a "nightmare."
FWIW, they did ask me for a lot of awfully detailed information about my current and past compensation packages and what other companies I was interviewing with. I mostly declined to provide that information, and they didn't push it.
