As a premium user, the website loading times are very slow. My code execution times are taking very long compared to last year. The site promises that we get faster execution times in there code execution platform, but that is a load of crap.
Leetcode has dropped the ball in terms of quality. They increase website traffic through daily challenges (which are repeats of old questions btw) but decide to screw existing premium users, because they are concerned about getting new subscriptions.
The only worty thing they have are the test cases. Your better off coding on a platform like coderpad, where the real interview will take place. Create your own test cases, & data structure classes then spend time on a slow platform like leetcode. It will improve you in the long run.
Suffice to say, I will not be renewing my subscription this year. I am sure a lot more people would be doing the same. Leetcode is coming a thing of the past, just like CTCI
