I recently found out about leetcode, and joined here only a little over a week ago.
While checking out this site it seems it is very geared towards interviews / jobs, so has this helped anyone in a significant way to prepare for interviews?

If so, what are the best oportunities on here that helped you the most? Do companies ask about LeetCode? Or is the grind something for personal reasons and something else helped more?

Thanks for the advice in advance.
