over the phone a couple of weeks later, I struggled with what to tell him. Be smarter? No, I knew he was brilliant. Be a better coder? No, his skills were on-par with some of the best I'd seen. Like many motivated candidates, he had prepared extensively. He had read K&R’s classic C book and he'd reviewed CLRS' famous algorithms textbook. He could describe in detail the myriad of ways of balancing a tree, and he could do things in C that no sane programmer should ever want to do. I had to tell him
