> But mostly... getting a CS degree these days teaches you what to say during interviews. For instance, I stepped a kid through linked lists when I was interviewing for a position at Amazon. He had, of course, never heard of them and confidently informed me that hash-tables were the answer to every computer science interview question (I did not go to work for that team at Amazon.)

My experience of comp sci and of FAANG questions lead me to believe that this is wrong (you do learn linked lists, even if you ignore them) and an outlier (FAANG interviews often have "implement a modified linked list" style questions.
