I've finished CS at Uni and I can tell you that now a few years down the line, I don't remember stuff. I only remember what I practice everyday, so if I am to pursue changing jobs I'll need to go off and recap what I've done at Uni. Same applies to a friend of mine that has over 15 years of experience, has a Uni degree in CS... and he had to go read Uni stuff that he's done 15 years ago just to go get another gig... his github repo has good projects and 1 project that has been stared for more than 4k times, he has an outstanding stackoverflow account etc but thats not enough... he still goes to companies and ask him to balance binary tries on the whiteboard to prove his worth...
