Code Signal

Also known as a developer assessment platform, CodeSignal offers a cloud-based technical skills screening software powered by professionally-designed skills evaluations and a proprietary predictive Coding Score.

In preparation for technical interviews, I discovered this platform that provides a code challenge in the form of an Arcade and a chance to compare myself with other developers.
