Codility

Codility makes software that helps companies assess developers during hiring and measure what their engineering teams can do. It focuses on skills evidence rather than resumes or university background.

Its platform aims to give recruiters and engineering managers accurate insight into real coding ability while keeping the candidate experience positive.

What Codility offers

• Coding tests — Skills-based assessments that filter candidates before technical interviews.
• Technical interviews — Live sessions that show how a candidate works.
• Realistic environment — Assessments run in a VS Code-based editor with package installation, a terminal and multi-file projects.
• Code analysis — Automated review of quality, maintainability and complexity.
• AI-aware tasks — lets employers decide how AI tools are allowed and includes tasks on prompting and checking AI-generated code.
• Integrity checks — Identity verification, impersonation detection and proctoring.
• Team capability view — shows what an existing engineering team can do.
