About CodeSignal

CodeSignal helps companies build the skills to succeed now, and adapt as the future of work changes. It’s the agentic skills intelligence platform, built on a simple belief: the biggest decisions about people should rely on proof, not proxies. For years, talent has been judged by resumes, titles, self-ratings, and inferred data, sources that only hint at what someone can really do. CodeSignal measures real skills through rigorous simulation-based assessments and in-depth evaluation of people’s actual work.

CodeSignal spans the full talent journey, from hiring assessments and AI interviews to hands-on skills development and workforce planning. With skills intelligence that measures work as it happens, leaders see where their teams stand, what to coach next, and where to plan ahead. It’s why companies like Capital One, Meta, and Dropbox, along with millions of people building their own skills, have made CodeSignal the standard for measuring what’s real.
