> Doesn't matter how long you spend on leetcode. Google will present you with a problem you haven't seen before and there are a huge amount of people who have done leetcode for years and can't pass the interview questions.
It matters how long you spent time on leetcode/other practices from popular algorithm books (comen, skiena, sedgewick). Source : friends, ex co-workers, and personal experience. Sometimes they just change the "story" questions but the algo and tricks are the same, sometime they took it verbatim from leetcode (or the other way around: someone leaked them to leetcode).
