Codility review

Codility is built for teams that want to see how engineers work with AI, not only whether they can solve a puzzle alone. Online plans start at $4,800 a year, or $800 a month for 25 invites, and include Screen and Interview, five platform users with unlimited collaborators, one standard ATS integration and integrity tools such as plagiarism detection, proctoring with snapshots and task leakage protection. Every plan includes Claude Code and Codex set up in the terminal and an AI Assistant on models up to Sonnet class, and each prompt, command and code change is saved with the result. Hiring teams can turn AI off for a task when they want to see unaided work. The task library grows with the plan and reaches the full 1,300+ validated tasks at 1,000 invites a year. Enterprise adds AI skills tasks for sales, marketing and finance roles, ID verification, video proctoring, SSO and every ATS integration, including Workday and SAP. The entry price is high for a team hiring a few engineers a year.
