Once you get into a FAANG company, do you actually use these algorithms? OOP/FP design, "clean code", the System design I would see as important, but in an actual dev job how much does the hard-core algorithm stuff come up?
Big O is always extremely relevant. - A lot of the typical algorithms in djikstra, merge sort etc. are not important to know by heart, but they represent important concepts to know to solve complex problems. Divide and Conquer and Greedy or topics that come up implicitly at least once a week, usually more often.
