• Secure Mode: Enforces full-screen testing with automatic violation recording

• Watermarking: Adds identifying marks to test questions to prevent sharing

Each feature can be toggled independently, allowing you to customize the security level based on your specific requirements and candidate experience preferences. (HackerRank Support)

Copy-Paste Tracking: Your First Line of Defense

Default Configuration and Behavior

Copy-paste tracking serves as the foundation of HackerRank's anti-cheating measures and is enabled by default for all tests. This feature monitors every instance when a candidate attempts to copy code from the assessment or paste content from external sources. (HackerRank Support)

The system tracks both successful copy-paste operations and attempted ones, providing valuable insights into candidate behavior patterns. When candidates try to copy code snippets to share with ChatGPT or other AI tools, these actions are immediately logged and made available in your post-assessment reports.

Interpreting Copy-Paste Data

The CSV report generated after each assessment includes a dedicated "Copy-Paste Frequency" column that helps you track the number of times a candidate tried to copy-paste code during their session. (HackerRank Support) This metric serves as a red flag for potential cheating attempts, especially when combined with other behavioral indicators.

High copy-paste frequency often correlates with:

• Attempts to share code with external AI tools

• Copying solutions from online resources

• Collaborative cheating with other individuals

• Legitimate code reuse within the assessment (which requires manual review)

Best Practices for Copy-Paste Monitoring

To maximize the effectiveness of copy-paste tracking:

1. Set Clear Expectations: Inform candidates that copy-paste actions are monitored and explain acceptable use cases (like copying their own code within the assessment)

2. Establish Thresholds: Define what constitutes suspicious copy-paste behavior based on your assessment length and complexity

3. Review Patterns: Look for unusual patterns like rapid copy-paste sequences followed by correct solutions

4. Combine with Other Metrics: Use copy-paste data alongside tab-switching and timing information for comprehensive analysis

Configuring Tab Proctoring for Maximum Security

Enabling Tab Proctoring

Unlike copy-paste tracking, tab proctoring is disabled by default for all tests, requiring manual activation for each assessment. (HackerRank Support) This feature detects when candidates navigate away from the test window, which is often the first step in accessing ChatGPT or other external resources.

To enable tab proctoring:

1. Navigate to your test settings during test creation or editing

2. Locate the "Test Integrity" section in the test configuration panel

3. Toggle the "Tab Proctoring" option to "Enabled"

4. Configure alert thresholds and violation policies

5. Save your settings before publishing the test

Understanding Tab-Switch Detection

Tab proctoring works by monitoring browser focus events and detecting when the assessment window loses focus. This occurs when candidates:

• Switch to another browser tab or window

• Alt-tab to different applications

• Open new browser windows

• Use keyboard shortcuts to navigate away from the test

Each violation is timestamped and recorded, providing a detailed timeline of when candidates potentially accessed external resources. (HackerRank Support)

Setting Alert Thresholds

Effective tab proctoring requires careful threshold configuration to balance security with candidate experience. Consider these factors when setting your policies:

Immediate Alerts: Configure instant notifications for any tab-switch event during critical assessment phases

Cumulative Thresholds: Set limits on total tab-switch events (e.g., more than 3 switches triggers a review flag)

Time-Based Analysis: Monitor the duration of tab-switches to identify extended periods away from the assessment

Pattern Recognition: Look for suspicious patterns like regular intervals that might indicate systematic cheating

Implementing Secure Mode for Full-Screen Lock

What Secure Mode Provides

Secure Mode represents HackerRank's most comprehensive approach to maintaining assessment integrity by implementing multiple protective measures simultaneously. (HackerRank Support) This feature creates a controlled testing environment that significantly reduces opportunities for candidates to access external resources like ChatGPT.

Enabling Secure Mode

When you enable Secure Mode, you establish a controlled testing environment that discourages unfair practices, ensuring candidates rely solely on their skills for fair evaluation. (HackerRank Support) The system automatically combines multiple security features into a unified protective framework.

To activate Secure Mode:

1. Access your test configuration settings

2. Navigate to the "Test Integrity" section

3. Enable the "Secure Mode" toggle

4. Review the automatically configured sub-features

5. Customize individual components if needed

6. Test the configuration with a sample assessment

Full-Screen Enforcement

When Secure Mode is enabled, candidates are required to take the test in full-screen mode, eliminating easy access to other applications or browser tabs. (HackerRank Support) This creates a significant barrier to accessing ChatGPT or other external AI tools during the assessment.

The full-screen requirement:

• Prevents casual tab-switching to AI tools

• Reduces visual distractions from other applications

• Creates a more focused testing environment

• Makes cheating attempts more deliberate and detectable

Violation Recording and Reporting

Attempts to exit full-screen mode are automatically recorded in the candidate report, providing transparency and aiding in identifying irregular behavior during the assessment. (HackerRank Support) This detailed logging enables post-assessment analysis and helps identify patterns of suspicious behavior.

Each violation record includes:

• Timestamp of the full-screen exit attempt

• Duration of time spent outside full-screen mode

• Method used to exit full-screen (if detectable)

• Subsequent actions taken by the candidate

Advanced Security: Watermarking and AI-Powered Proctoring

Question Watermarking

To address the challenge of candidates sharing test questions externally, HackerRank allows watermarks to be added to questions within a test. (HackerRank Support) This feature helps track the source of leaked questions and provides legal recourse against unauthorized sharing.

Watermarking works by:

• Adding unique identifiers to each question instance

• Tracking which candidate received which watermarked version

• Enabling identification of the source when questions appear online

• Deterring candidates from sharing questions with AI tools or online forums

Proctor Mode: AI-Powered Supervision

For organizations requiring the highest level of security, HackerRank offers Proctor Mode, an AI-powered feature that simulates live human proctoring to help ensure test integrity.
