Most interviews in other industries try to figure out how much a person knows at that point in time. Software interviews try to do the impossible and try to figure out how quickly someone learns. That’s because this can be gamed, as you mentioned. I know people that have memorized 800 leetcode questions and got jobs at all the FAANGs, even though they were average developers. For the record I’ve never gotten into FAANG (although I have gotten into FAANG-adjacent) so my evaluation should be taken with a grain of salt. The best interview is one that can’t be gamed. Just like Hollywood auditions. Give the people the script and see how well they do. Tell the interview candidate you are going to give them 3 questions and they pick the one they want to do, even if they know it already. This strips away all pretense that they are figuring it out on the spot. At least then you are on a level playing field.
