Codility Developer Training vs. Immersive

Codility Developer Training is the free practice platform Codility runs for individual developers. Work through programming lessons, timed challenges, and exercises across common languages, algorithms, and data structures, with immediate feedback on whether a solution is correct and how it performs. Developers use it to sharpen fundamentals and prepare for technical interviews, at their own pace. This is a separate offering from the Codility assessment platform that organizations buy.
