I did a couple FAANG interviews last year, and I was pleasantly surprised. The coding questions were novel (so no needing to memorize tons of existing questions) and non trivial, but did NOT require obscure algorithmic knowledge or esoteric math. They wanted lots of working code, and for you to explain your thought process. So I was definitely happy I practiced on hackerrank and leet code, and think anyone would still need to practice coding under some time pressure, but it was a nice experience. Contrast that to Microsoft interviews where they would just straight up ask me "code a way to find the shortest path in a graph". "Merge two streams in optimal time". just asking for me to implement code straight from Algorithm textbooks and hackerrank questions.
