The ability to blur your background in Jobma depends on whether your employer has enabled this feature for you. 

If they have, the video background will be automatically blurred."

I am stuck on the Microphone and Webcam check page. It keeps loading.

In case you’re stuck on the microphone and webcam check page and it keeps loading, follow these steps:

• Close any other programs that might be using the webcam and microphone.
• Close any other duplicate interview links that might be open.
• Refresh the interview page, and if you see a prompt to allow access to your camera and microphone, please allow it. 
• You can also try opening the link in an Incognito Window.
• If these steps don’t work, you can try switching the browser.
