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. That platform covers technical screening, structured live technical interviews, AI skills assessment, and verified skills mapping across engineering teams. Codility Developer Training carries no hiring workflow, no candidate reporting, and no administrator controls. It is built for one developer practising alone, and it is free to use.
