HackerRank · HackerRank Chakra: Agentic AI Interviewer for Technical Hiring

Open HackerRank Chakra

Chakra is HackerRank's AI interviewer: it builds an interview from a job description, runs the whole voice interview on its own (including hands-on coding work with follow-up questions about the candidate's approach), monitors integrity, and writes a scored report that cites the transcript. It is for recruiting and engineering hiring teams that want to replace early live screening rounds without losing evidence they can review.

Best for

Recruiting teams and engineering hiring managers, especially those already on HackerRank, who run many first-round technical interviews and want each candidate's hands-on work, AI fluency and follow-up answers captured in a scored, evidence-linked report

Not ideal for

Teams that hire only a few people a year, organizations that want published per-interview pricing, companies or candidate pools uncomfortable with webcam and screen proctoring, and hiring processes that need a human interviewer in every round

Who it's for

Recruiters, talent acquisition teams and engineering hiring managers running technical and AI-era interviews at scale

Capabilities

  • Builds an interview from a job description or role prompt, typed or spoken: Chakra identifies the required skills and drafts sections, time per section, evaluation goals and sample questions
  • Refine the interview plan by prompting it (reorder sections, change a section's focus or question types), and mark must-have requirements that get more weight in scoring
  • Use your own questions or pick from the Chakra question library
  • Runs the full interview by voice without a human interviewer: introduces the agenda, asks follow-up questions in real time, adapts questions to the candidate's answers and manages time across sections
  • Hands-on sections: an in-line code editor where candidates write, edit and run code, and (per the product page) a development canvas with a real codebase and an AI coding assistant
  • Asks follow-up questions about the candidate's submitted work to test reasoning, trade-offs and how they worked with AI
  • Candidate reports with an overall 5-point score, per-section scores, a strengths and gaps summary, and bullet points linked to timestamped transcript evidence
  • Full session recording of the candidate's screen and webcam with a synced, downloadable transcript, plus CSV export of scores and summaries for all candidates
  • Integrity signals: full-screen exits and extra monitors pause the interview, and face detection, phone and tablet detection on camera, and screenshot analysis for unauthorized tools are logged with evidence
  • Optional HackerRank Desktop App Mode (Windows and macOS) that blocks other applications, screen sharing, screenshots, extra monitors, virtual machines and copy-paste during the interview
  • Invites by email template with expiry dates, bulk CSV upload, a shareable interview link, or an ATS stage
  • Documented ATS integrations with Greenhouse, Workday and Ashby, an API for interview reports and candidate data, and a Chakra MCP server

Limitations

  • No public price list: HackerRank says Chakra is priced per interview attempt with volume discounts, but it does not publish the rates
  • HackerRank's ATS integration guides list an active Chakra account, enabled through HackerRank support, as a prerequisite
  • Candidates must grant webcam, microphone and screen-sharing access, and Desktop App Mode also requires installing an app with system permissions; some candidates may object to this level of monitoring
  • The Desktop App is documented for Windows and macOS only, and it will not run inside a virtual machine
  • HackerRank says Chakra is best experienced on desktop
  • Reports are only available for candidates who complete the interview
  • Accuracy and consistency claims on the product page describe HackerRank's own process; HackerRank says it runs bias analyses with third-party auditors under NYC Local Law 144, but the Chakra page does not link audit results
  • Chakra scores and recommends; your team still makes and is accountable for hiring decisions, and AI use in hiring can carry notice or audit rules in some jurisdictions
  • ATS guides are published for Greenhouse, Workday and Ashby; check other ATS platforms with HackerRank before you buy
  • No self-hosted deployment is documented

Use cases

  • Replacing a recruiter phone screen and take-home for software engineering roles with one AI-run interview that includes hands-on work
  • Testing how candidates plan, use an AI coding assistant and defend their changes in a real codebase
  • Running consistent first-round interviews for a high-volume or campus hiring drive
  • Turning a new role's job description into a structured interview with weighted must-have skills
  • Adding an AI interview stage to a Greenhouse, Workday or Ashby interview plan so invites and scores flow through the ATS
  • Reviewing flagged integrity events with screenshots and recordings before advancing a candidate

Our take

Chakra's main idea is that an AI interviewer should watch candidates do the work and then question them about it, not just score how well they talk. The setup flow, evidence-linked reports and ATS hooks make it practical for teams already running high-volume technical screens, especially on HackerRank. Before you rely on it, check three things: whether the per-attempt cost beats your current screening rounds, how its scores compare with your own interviewers' scores on a pilot role, and whether your candidates and local rules are comfortable with the level of proctoring it uses.

Who should use it

Talent acquisition teams and engineering managers who spend significant engineer time on first-round technical interviews, want to measure how candidates work with AI tools, and can pilot it on one role and compare its scores with their own interviewers'.

Who should skip it

Small teams with occasional hires, companies that need a published per-interview price before talking to sales, employers whose candidates or policies rule out webcam and screen monitoring, and processes where a human must conduct every interview round.

Strengths

  • Candidates do hands-on work and then defend it, rather than only answering voice questions
  • Interview setup starts from a job description and is refined by prompting
  • Every score links back to timestamped transcript evidence and a full recording
  • Detailed integrity signals, with an optional locked-down desktop app
  • Documented Greenhouse, Workday and Ashby integrations, plus an API and MCP server

Weaknesses

  • Per-attempt rates are not published
  • Heavy candidate monitoring (webcam, screen, microphone) that some candidates dislike
  • Scoring accuracy and fairness claims are vendor-reported
  • Desktop App Mode is Windows and macOS only
  • No self-hosted option documented

Where HackerRank Chakra excels

First-round screening for engineering roles

One Chakra interview can cover conversation, hands-on coding and follow-up questions, and the evidence-linked report lets an engineer review a candidate in minutes instead of joining a live call.

Assessing AI fluency

In the development canvas shown on HackerRank's product page, candidates work in a repository with an AI coding assistant and then have to explain their choices, which shows whether they understand the AI's output or just accept it.

High-volume or campus hiring

Chakra runs interviews whenever candidates are ready, applies the same rubric to each one, and sends invites and scores through Greenhouse, Workday or Ashby.

Frequently asked questions

What is HackerRank Chakra?

Chakra is HackerRank's AI interviewer. It creates an interview plan from a job description, conducts the interview by voice on its own, has candidates do hands-on work such as coding in an editor or a development canvas, asks follow-up questions about their approach, monitors integrity, and produces a scored report backed by transcript evidence.

How much does Chakra cost?

HackerRank says Chakra is priced per interview attempt, with volume discounts as usage grows, but it does not publish the per-attempt rates. The Chakra page offers a free trial and a demo booking.

Does Chakra make the hiring decision?

No. Chakra scores candidates and gives a recommendation with supporting evidence. HackerRank's AI features page describes the Reporting Agent's output as a structured evaluation report for human review, and HackerRank's CEO told TechCrunch that the final hiring decision remains with humans.

How does Chakra prevent cheating?

It pauses the interview if the candidate leaves full-screen mode, connects another monitor or moves out of webcam view, and it logs missing or extra faces, phones and tablets on camera, and screenshots showing unauthorized tools such as AI assistants. An optional desktop app for Windows and macOS also blocks other applications, screen sharing, screenshots, virtual machines and copy-paste.

Which ATS does Chakra integrate with?

HackerRank publishes Chakra integration guides for Greenhouse, Workday and Ashby, and its blog also lists Eightfold. Chakra has an API for interview reports and candidate data and a Chakra MCP server.

Which AI models does Chakra use?

HackerRank's AI features page lists Anthropic Claude for the Interview Creator Agent and the live Interviewer Agent, and OpenAI for the Reporting Agent that evaluates completed interviews. Integrity features use Amazon Rekognition, Google Gemini and OpenAI. HackerRank says candidate data is never used to train AI models.

Is Chakra only for software engineers?

No. HackerRank's documentation says Chakra runs interviews for technical and non-technical roles. Its hands-on coding and development canvas features are aimed at engineering and AI roles, and the sample interviews on the product page cover AI engineers, forward deployed engineers, customer experience engineers and AI product managers.

About HackerRank Chakra

Chakra sits inside HackerRank's hiring platform as a separate AI interviewer product, alongside its Screen take-home assessments and its live Interview product. A recruiter pastes or dictates a job description, answers a few follow-up prompts (experience level, location, must-have and nice-to-have skills), and Chakra drafts an interview plan with sections, time per section, evaluation goals and sample questions. You can reorder or refocus that plan by prompting it, mark requirements as must-have so they carry more weight in scoring, and try the interview yourself as a candidate before sending invites by email, CSV upload, a shareable link, or an ATS stage. The candidate then talks with Chakra by voice. It introduces the agenda, asks planned questions, probes deeper on answers, and keeps time across sections. For coding questions it opens an in-line editor where the candidate writes and runs code, and the product page shows a canvas with a real repository and an AI coding assistant in which candidates plan and fix tickets. After the work is submitted, Chakra asks follow-up questions about the approach and trade-offs, which is the main difference from voice-only AI screeners. The report gives an overall score and per-section scores on a 5-point scale, a summary of strengths and gaps, bullet points linked to timestamped transcript evidence, a full screen and webcam recording with a synced transcript, and a list of integrity flags with screenshots or webcam images. Integrity checks cover full-screen exits, extra monitors, missing or extra faces, phones and tablets on camera, and screenshots that show unauthorized tools; an optional Windows and macOS desktop app adds a locked-down mode that blocks other apps, screen sharing, VMs and copy-paste. HackerRank's AI features page says the interview-creation and live interviewer agents run on Anthropic Claude and the reporting agent on OpenAI. Documented integrations cover Greenhouse, Workday and Ashby, HackerRank's blog also names Eightfold, and there is an API for reports plus a Chakra MCP server. The trade-offs: HackerRank says pricing is per interview attempt with volume discounts but does not publish rates, candidates must accept webcam, microphone and screen monitoring, and the scoring-accuracy and fairness work described on the product page is HackerRank's own account. Chakra produces scores and recommendations; per HackerRank's CEO in TechCrunch, the hiring decision stays with people.
