Definitely TOP SCHOOL though. I've met and worked with many PhD CS students from the lower end of the spectrum who were nothing more than book smart, in the worst way. I guess lower and mid tier schools just don't require real innovative thought out of their graduate students. They couldn't apply their knowledge in any way to solve any problem. Their graduate work was neither innovative in a scientific or practical fashion. They were relegated to business analysis & project management at a major corporation. Yuck.
