What are all those corner cases and hard problems? I routinely ask interview subjects to write code to manage a linked list (it was a small part of a problem in a previous job), and I've been asked to write a ll class. Writing a linked list is like hiring someone to be a professional driver, and you want to make sure they know that you can change tires, and that one should adjust mirrors to be able to see behind the car.
