It's not the same knowing something by memory than really know how things work from the inside. Sure, a bubble sort must be something really basic, but it's something that is though to students to train them to elaborate algorithms just right. On the professional field, is it really necessary to know this or any sorting method?
It's like knowing by memory how to factorize an equation instead of understanding the logic behind the operation. At the end, is just an exercise but not a parameter to qualigy if someone is a professional or not.
