Hi, I am on top 10 at 10th place of this very nice site. I like the simplicity of this place. It is very nice and clean without advertisements or other unnecessary stuff. I checked only participants from Poland, and on that Leaderboard filtered, I achieved my goal in the top 10. I am thrilled about that. and HackerRank site is in my opinion very nice place to improve coding skills. But I am not sure how long I will be in the top 10th. To check the current status, you can click on the picture below. That is a screen from today filtered for Poland only. On the global Leaderboard, I am in 989th place, but still in the top 1000 :P. I only wish for that site to have a blog engine widget to show the current rank in World and Poland :). But still, it is my favorite code puzzle site. Do you like other kinds of places?
