CodeSignal is a skills intelligence platform that helps hiring teams validate, assess, interview, and develop technical and business skills with AI-driven tools.
About
CodeSignal is a skills intelligence and validation platform used by organizations to measure, evaluate, and develop job-related skills with evidence rather than proxies such as resumes. The company positions its product around "agentic" skills validation, meaning AI agents assist across screening, assessment, interviewing, and learning. It is best known for technical hiring assessments and has since expanded into business, behavioral, and agentic-skill evaluations, plus live interviews and structured upskilling.
The platform works by combining validated skills assessments, an AI interviewer that can conduct phone screens and video interviews, live technical interview sessions in a coding environment, and skills development content. A skills intelligence layer aggregates data points so teams can benchmark talent, spot gaps, and plan hiring or reskilling. CodeSignal also includes cheating and fraud prevention features and offers a partner and integrations ecosystem. Organizations across technology, financial services, healthcare, higher education, and government use it for hiring, university recruiting, talent mobility, and interviewer training.
