Value proposition
Helps companies hire and upskill developers on skills rather than pedigree. Chakra merges the recruiter screen, take-home test and engineer interview into one agentic AI interview built on real-world code repositories.
Products and solutions
Chakra (agentic AI interviewer, GA Oct 2026), Screen (technical assessments), Interview (live coding interviews), Engage (tech employer branding), SkillUp (internal talent mobility), Certified Assessments, AI plagiarism detection / Integrity Signals, AI Data Services / Human Data
Unique value
Measures how candidates think and work with AI, not just whether they produce a correct answer. It does this using real repositories, an in-canvas AI assistant and context-aware follow-up questions. HackerRank reports 70-80% fewer suspicious-activity flags than in its traditional assessments.
Target customer
Enterprise and tech-company engineering and talent acquisition teams hiring software developers. It also serves a community of 26M-30M+ developers.
Industries served
Technology, financial services/banking, retail, automotive, IT services/consulting, cross-industry technical hiring
Technology advantage
Large proprietary dataset from 172,800 daily skill assessments and a developer community of more than 26M. Chakra ran over 500K beta interviews. The company has an installed base of 2,500-3,000+ business customers and an integrity/proctoring stack built for regulated hiring, including NYC AEDT bias-audit compliance.
How they differentiate
Has a full agentic AI interviewer that runs first rounds end-to-end. By contrast, Codility does not build an AI recruiter interview and instead offers an AI Copilot. HackerRank also has the largest developer community and a combined integrity scoring stack.
