CodeFights is now CodeSignal. If you don’t know CodeFights, the site launched back in 2014 as a platform for developers to compete in coding competitions. Along with the new name comes a scoring system the company calls Coding Score. Similar to a credit score, this system is put in place to tag developers with an overall grade compared to peers. The Coding Score also serves as a way for employers to find the best talent. Scores range from 300 to 850.
