I work at FAANG - my take is, all questions can be solved based on these 10-15 data structures / algorithms. They are just gift wrapped with a lot of fluff, but underlying each of them is one or a combination of one of these data structures / algos.

As an aside, to everyone who has asked me how to get into FAANG - I always say you should be able to code DFS/BFS in your sleep like your life depends on it. 1/5 questions is surely going to be a tree/graph search.
