CodinGame

CodinGame is a technology company editing an online platform for developers, allowing them to play with programming with increasingly difficult puzzles, to learn to code better with an online programming application supporting twenty-five programming languages, and to compete in multiplayer programming contests involving timed artificial intelligence, or code golf challenges.

CodinGame also serves as a recruiting platform, allowing developers to get noticed by companies based on their performance on the contests.
