Chakra

Chakra is HackerRank’s agentic interviewer for screening candidates through realistic, AI-enabled work. Candidates explore an existing codebase, plan and build with an AI agent, and explain their solution and reasoning. Chakra asks follow-up questions based on candidates’ work and evaluates problem-solving, AI fluency, and judgment. Reports provide scores, strengths, gaps, and supporting evidence, with integrity signals for responses that may rely on LLM-generated answers. Teams can create custom coding questions and choose alternative questions for interviews.
