I just launched a new free SQL practice platform today called DataLemur! I'm the author of Ace the Data Science Interview, and a lot of our readers wanted to practice the SQL questions from the book, so we decided to make DataLemur free and open! Even if you aren't job hunting, these tricky SQL questions are pretty fun to practice on.
