Comp sci programs indeed don't teach that, that's right. On the other hand, a lot of college grads have taught themselves to code effectively in their own time, either in open source or by selling their own apps. These are generally bright amd well-motivated, and have experience in diverse areas of programming. It's a matter of picking the right people.
