Using them and understanding them are still a lot different than memorizing them to the point of working with them on a whiteboard in a google gang bang interview. I reviewed lots of CS papers while in uni and it only took a quick search to confirm the algorithm was what I had in mind. Completely unnecessary to memorize each one.
