> They're trying to filter out candidates who would need to grind leetcode in order to explain how a hash table works Well if anything they select these people because grinding leetcode does work Why do they presumably even need to select people who doesn't need to prepare to do a specific job? Is that because at those companies you're supposed to do that kind of work without preparation? I don't think that's anything more than what you think they think.
