This is why I don't hire CS grads to program. They are not taught what they need to know. They spend most of their time on things they would need to know to get into grad school to learn to be professors, and then not teach what people I would hire need to know.

My first question is always about effects of caches, and what-all kinds of caches affect what their program does. It is not all a programmer needs to know, but it separates those who care about what affects their programs from those who don't.
