It seems to me that while passing a leetcode question shows that you might know a thing or two, not passing one doesn't really show the opposite. You could be the smartest / greatest coder ever and you just got a really unlucky question... Or it could be that you're not great when you are nervous, etc...

Also, a lot of the time it feels like the answer to most leetcode problem is some sort of trick.... and if you think of it you are golden and if you don't it sucks to be you. Most of the time I'm trying to write code that is NOT tricky... So in some ways I think the job itself will train you to seek simple clean solutions as opposed to tricks.
