Builds trust in every assessment

Integrity isn’t about whether candidates use AI or not. It’s about fairness, making sure everyone follows the same rules, and knowing you can trust the results. HackerRank’s Integrity Stack helps you create a level playing field, ensure candidates adhere to your assessment policies, and give your teams the evidence they need to make confident decisions.

Prevent

Create a secure environment that blocks unauthorized tools, content leaks, and prevents candidates from accessing unapproved references or assistance.

Detect

Monitor assessments live with proctoring that watches candidate activity and steps in right away if any rules are broken.

Verify

Combine AI-powered plagiarism detection, screenshot analysis, and clear evidence in reports to confirm every submission and build trust in your decisions.

Prevent

Maintain fairness from the first click

Watermarking and shuffle questions: Personalize and randomize content to reduce the chance of sharing and help protect question integrity over time.
Secure Mode: Keep assessments in fullscreen and track any exits or tab switch. Clear prompts guide candidates back to focus and reinforce fairness for every candidate.
HackerRank App (coming soon): The HackerRank App runs at the application layer to create a secure, dedicated environment for assessments and interviews. It locks down other applications, enforces fullscreen mode, and blocks screenshots or screen sharing. With built-in proctoring and detailed reporting, it offers stronger protection and trust than browser-based solutions.

Detect

Spot issues in real time

Even with prevention in place, suspicious behavior can happen. HackerRank’s detection tools continuously monitor assessments as they unfold:

Proctor Mode: Proctor mode is like having a human proctor for take-home assessments. It sets the test instructions, detects suspicious activity in real time, and submits a comprehensive report that includes a full-session replay.
Live image analysis: Confirm candidate's identity and verifies that the candidate remains present and alone, flagging any time their face is not visible or someone else appears.
Real-Time alerts: When a candidate violates rules, like attempting to exit fullscreen, your team receives instant notifications so you can intervene or review as needed.

Verify

Validate results with confidence

After the assessment, you can validate that each result is genuine, consistent, and truly reflects the candidate’s own work

AI-Powered Plagiarism Detection: A proprietary model trained on real examples of LLM-based and traditional plagiarism, this model analyzes behavioral signals and code similarity to surface high-confidence plagiarism flags.
Session Replay: A complete visual timeline of candidate actions, so you can see exactly what happened.
Photo ID Verification: Confirms identity by matching the candidate’s photo to an official ID and capturing periodic snapshots.

A complete integrity stack that you can trust.
