HackerRank is a developer skills platform used by companies to screen, interview, and upskill technical talent, and by more than 26 million developers to practice coding and earn skill certifications. Its products include Screen (automated coding assessments), Interview (collaborative real-time coding interviews), Engage (technical hiring events and hackathons), and SkillUp. HackerRank for Work exposes a public REST API (v3) so customers can programmatically manage tests, candidates, questions, interviews, and results, and integrate assessments into their own applicant-tracking and hiring workflows. This API Evangelist profile catalogs HackerRank's developer surface and the enrichment artifacts derived from it.
