Job-simulation skill assessments for the AI hiring era
Generate role-specific assessments from a job description and score open-ended answers with pre-trained or custom AI agents.
Evaluate candidates' AI knowledge, prompting skill, judgment and responsible-use habits with ready-made or custom tests.
Let candidates use tools like Claude, ChatGPT and Codex inside a monitored assessment to see how they really work with AI.
Detect pasting, tab switching, full-screen exits, second screens and IP changes, with optional webcam monitoring for identity checks.
Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
