HackerRank has made Chakra generally available, an artificial intelligence agent designed to conduct technical interviews for software developers. The platform, which serves thousands of enterprise customers, is using the new tool to shift hiring evaluations from simple code correctness to a broader assessment of candidate judgment and problem-solving processes.
Following a six-month beta period, the company reports that Chakra has already facilitated more than 500,000 interviews. Early adopters include technology firms such as Snowflake, Snorkel, and Capgemini, alongside internal testing by HackerRank itself.
Chakra AI Interviewer Process
The system operates by placing candidates in a simulated work environment rather than a traditional testing format. Candidates receive a task based on a real-world code repository and work through it within a canvas that includes an integrated AI assistant. As the candidate codes, Chakra monitors their actions and asks follow-up questions to understand their decision-making.
For example, the AI might ask why a specific approach was chosen over another or how the solution would adapt to new constraints. This method allows the system to evaluate “AI fluency,” a metric that measures how well a candidate frames problems for AI, judges its output, and steers it toward a solution.
Vivek Ravisankar, co-founder and CEO of HackerRank, stated that the previous model of evaluation focused primarily on the final output. He noted that because AI tools can now generate code artifacts easily, the critical question for employers has shifted to understanding the thinking and judgment behind that output.
Impact on Developer Hiring Tools
Chakra consolidates what was previously a multi-stage hiring process into a single interview session. Ravisankar explained that the traditional workflow, which typically involved a recruiter screen, a take-home assessment, and a follow-up engineering interview, is now replaced by this unified AI-driven interaction.
The company claims that allowing candidates to use AI during the interview actually reduces cheating. According to Ravisankar, suspicious activity flags dropped by 70% to 80% in Chakra interviews compared to standard HackerRank assessments. The reasoning is that providing official access to AI tools removes the incentive for candidates to secretly use outside resources to find answers.
This launch represents a strategic pivot for the Y Combinator-backed startup. HackerRank built its business on coding challenges that tested raw technical skill. Ravisankar compared the transition to Apple moving from the iPod to the iPhone, suggesting that while the old assessment model still holds value, Chakra represents the future direction of the market.
Regulatory and Bias Considerations
Delegating hiring decisions to algorithms introduces complex regulatory challenges. Automated employment tools can inherit biases from their training data or the criteria used to build them. In response, HackerRank designed Chakra to score candidates rather than make final hiring decisions, leaving the ultimate choice to human recruiters.
Ravisankar argued that a properly tuned AI system can be less biased than humans because it applies the same rubric consistently to every candidate, unaffected by factors like background or education. However, regulators remain cautious. New York City, for instance, requires employers using automated employment decision tools to conduct independent bias audits and notify candidates in advance.
HackerRank acknowledged that compliance with these regulations is a core part of the product’s development. The company currently serves over 3,000 business customers, including Amazon and Nvidia, and supports a community of more than 30 million developers globally. Chakra is now available to these customers as the standard for technical evaluation.
