Interview Portal: Testing Your Hardware

Before any interviews, it's important to ensure your computer and internet connection are properly set up. Take a few moments to test your hardware directly in the Interview Portal using the Test Hardware feature.

  • For applicants and interviewers: this feature is located below the calendar on the Homepage.

  • For program managers and directors: this feature is at the top of the Meeting Rooms section.

When you click Test Hardware, you're placed in a test session where you can adjust audio and video controls. Use the More actions option to access specific Settings.

Alternatively, you can test your hardware at https://test.8x8.vc. After completing the test, results display with color-coded indicators:

  • Green: your system meets all the requirements. No further action is needed.
  • Yellow: your system meets the minimum requirements. Performance should be adequate, but you might experience minor issues.
    • Note that a yellow result from the “IPv6 enabled” or “Reflexive connectivity” test items will not impact your experience and can be safely ignored.
  • Red: there is an issue with your setup that may prevent a smooth interview experience. Refer to your browser's help content for troubleshooting guidance.

Troubleshooting Tips

If you’re experiencing audio or video issues, the problem is likely with your system, network connection, or another local factor. Try these steps to fix the issue:

  1. Check your internet connection.
    • Test your internet speed using an online tool such as speedtest.net. Generally, an optimal experience requires a download speed of at least 10 Mbps and an upload speed of 3 Mbps
    • Switch to a different Wi-Fi network or use a wired Ethernet connection for better stability.
    • If your connection is weak, move closer to your router.
  2. Turn off VPN.
    • VPNs can interfere with performance. Temporarily disable it and try again.
  3. Close unnecessary programs.
    • Running too many programs can slow down your device and impact audio/video. Close anything you’re not actively using.
  4. Clear your browser’s cache and cookies.
    • Old or corrupted data can cause issues. Refresh your browser by clearing the cache and cookies, then restart it.
  5. Ensure your browser is up to date.
    • Check for updates and install the latest version.
  6. Try a different browser
    • If issues persist, try switching to another browser.
  7. Restart your device.
    • A simple reboot can often resolve performance problems.
  8. Verify your equipment settings
    • Make sure your camera, microphone, and speakers are set up correctly and aren't muted or turned off.
  9. Refer to your browser's help content.
    • If the above steps don't resolve the issue, refer to your browser's help content (e.g., Google Chrome's help articles).

Compatible Browsers 

A web browser is the program your computer uses to connect to the Internet and access ResidencyCAS.

Chrome and Firefox (Preferred)

For the optimum experience, we recommend using the most current version of Mozilla Firefox or Google Chrome, which work on both Macs and PCs. You can download these browsers for free here:

Safari

Safari is the default internet browser for Apple products and is compatible with ResidencyCAS. If you encounter any difficulty while using the most up-to-date version of Safari, try switching to Chrome or Firefox.

Edge

Edge is Microsoft’s most recent browser and is compatible with ResidencyCAS. If you encounter any difficulty while using the most up-to-date version of Edge, try switching to Chrome or Firefox.

Internet Explorer

As of June 15, 2022, Internet Explorer is no longer supported by Microsoft. Switch to a supported browser to access ResidencyCAS.

Troubleshooting

If you are having difficulty loading ResidencyCAS:

  • Ensure you are using the most current version of a compatible browser, which should support a minimum security standard of TLS 1.2. Most modern browsers already meet this requirement, but if you’re unsure or experiencing issues, you may need to refer to your browser’s help content or consider updating to a newer version.
  • Confirm that Cookies, JavaScript, and Pop-ups are enabled within your browser.
  • Be aware if you are using public Wi-Fi (e.g., libraries, coffee shops), connection speeds may slow down the portal.

To determine your browser's version, and to confirm that Cookies, JavaScript, and Pop-up windows are enabled, visit http://whatismybrowser.com.

Safe-List IP Addresses

If you’re having trouble accessing a portal and encounter error messages such as "access denied," "connection timed out," or "unable to connect to the server," it’s possible that a firewall is blocking your access. Another telltale sign of a firewall issue is if you can access the platform without problems on a different network, like your home network or mobile data.

To address this, ResidencyCAS employs Amazon Web Services (AWS) to ensure reliable access. We've compiled a table of IP addresses below that your IT department should safe-list to prevent these connectivity issues. Please be aware that AWS may periodically update these IP addresses. Additionally, your institution's software must have a minimum of version TLS 1.2 to establish a secure connection.
