This article provides best practices for running group assessments in Proctor Mode, where multiple candidates take the assessment simultaneously at a shared physical location. Following these guidelines helps ensure a smooth, stable, and fair assessment experience for all candidates.

Prepare candidate systems in advance

Verify that each candidate system meets the minimum technical requirements before the assessment begins.

• RAM: Minimum 4 GB

• Operating system: Updated with the latest system and security updates

Ensure a stable internet connection

A reliable internet connection is critical when multiple candidates take an assessment simultaneously.

• Minimum bandwidth: 5 Mbps per candidate

• Recommended bandwidth: 10 Mbps per candidate for optimal performance

Use the following formula to calculate the required bandwidth based on the number of candidates to avoid network congestion.

5 Mbps × (number of candidates ÷ 2)

For example, if 100 candidates connect simultaneously, the required bandwidth is:

5 Mbps × (100 ÷ 2) = 250 Mbps

Use supported web browsers

Using supported browsers helps prevent compatibility issues and ensures consistent performance.

• Use the latest version of Google Chrome or Microsoft Edge

• Do not use unsupported or outdated browsers

Manage browser extensions

Browser extensions can interfere with the assessment experience and Proctor Mode checks.

• Disable or remove all unnecessary browser extensions

• Ask candidates to use Incognito or Private mode to prevent extensions from running during the assessment

Optimize the test environment on each system

Reduce system load and distractions before the assessment starts.

Ask candidates to:

• Close all other applications

• Keep only the HackerRank assessment tab open

• Refresh the browser page if the assessment becomes slow or unresponsive

Set up webcams

Prepare webcams before the assessment starts to meet Proctor Mode requirements.

• Use a functioning built-in or external webcam

• Test the webcam in advance at https://webcamtests.com/

• Uninstall any virtual camera software to prevent conflicts

Set up lighting

Proper lighting ensures clear webcam visibility throughout the assessment.

• Seat candidates in a well-lit area

• Ensure the candidate’s face is clearly visible at all times

• Avoid strong backlighting, such as bright windows or light sources behind the candidate

Prepare the physical environment

A controlled physical environment helps minimize distractions and maintain assessment integrity.

• Use a quiet, controlled space

• Minimize interruptions and background noise

• Ensure adequate spacing between candidates to maintain focus and assessment integrity
