Live Coding Challenges with AI Evaluation
Assess technical skills with real-time code evaluation. From algorithm problems to system design, measure what matters.
Evaluate coding skills beyond just correctness
Technical Assessment Done Right
Multiple Languages
Support for Python, JavaScript, TypeScript, Java, C++, Go, Ruby, and more. Candidates code in their preferred language.
Algorithm Challenges
Library of algorithm and data structure problems. From easy warm-ups to hard system design questions.
Real-Time Evaluation
AI evaluates code as candidates type. See correctness, efficiency, and code quality in real-time.
Code Quality Scoring
Beyond correctness—AI scores readability, maintainability, and adherence to best practices.
Edge Case Detection
AI identifies whether candidates handle edge cases, null inputs, and boundary conditions.
System Design Mode
For senior roles, conduct architecture and system design interviews with diagram support.
