FAANG nowadays wants you to be able to solve 2 leetcode mediums (or an easy+hard) without errors and with optimal computational complexity in 35 minutes. This is done up to three times so that's six problems and if you miss even one you likely fail the whole thing. To me that's really really hard unless you study to the point of having the solutions memorized. It's not the problems that are difficult per say but the time constraint which means going down the wrong path leaves you with no time to fix things.
