My company requires just easy leet code exercises. If you can pass that and you can hold your technical discussions - the stuff you have on your resume is likely true. If I interview someone it's because I like their past experience and think they are a good fit and/or have growth potential. I just need to know if they're lying and if they fit the team personality wise. What knowledge do I have to gain in having them do medium & hards besides that they can solve medium & hard exercises, which aren't really applicable day to day? This is equivalent to fizzbuzz without fizzbuzz. But that's just my opinion and I do not work at a FAANG...
