Leetcode didn't exist before "anti discrimination" laws. It was created specifically to give corps a legal barrier to defend against suit because the Fed wrote the law in such a way that you can easily and successfully sue any company for discrimination during the hiring process. So they filter out as hard as they can in a "neutral" way. You can see the effect in realtime. Google products are worse than they were 10 years ago when they have good devs that cared. They left and now it's just gears in a machine someone else made.
