>As a tech lead, I'm not interested in if you know what a double linked list is Well, I have a math degree, and when I interviewed for quant roles that involved coding as a secondary task I definitely needed to know what a double linked list is(along with BFS/DFS, sorting algorithms, dynamic programming principles, etc). I think double linked list is a bad example because every single decent CS degree would have a datastructures/algorithms class that would definitely cover linked lists in a lot of detail. I do agree with your overall point, at the end of the day saying "I read Introduction to Algorithms" has 0 value unless you have a decent GitHub to go along with it.
