Overview
CodeSignal is a skills platform for hiring assessments and AI interviews, plus a separate Learn product for individuals. Hire plans meter assessments and interviews as credits. Build is for small technical teams: 2,000 questions, Universal and Core Tech assessments, and Product, Design, and Engineering AI interviewers with proctoring and ID checks. Grow adds go-to-market assessments, more AI interviewers, and basic ATS integrations.
Hiring teams pick CodeSignal to run certified screens without a custom study on day one. Build is $79/mo billed annually ($948/year, 60 credits) or $99/mo monthly (5 credits). Grow is $479/mo annual or $599/mo monthly. Pro is custom, with the full library, fraud controls, and enterprise ATS connections. Learn is free for individuals, with Cosmo+ at $24.99/mo, which is not the hiring product.
