If you're unable to use camera on the interview website with Android, here's what you can do.
The most frequent issue is a "blocked" permission. Even if you clicked "Allow" once, your settings might be preventing access.
In Chrome: Tap the three dots (⋮) in the top-right corner > Settings > Site Settings > Camera.
Ensure the toggle is on, and check the "Blocked" list to make sure the interview site isn't accidentally listed there.
Google Chrome
Open Settings
Select Apps
Select App Management
Select your preferred browser (e.g. Chrome)
Select Permissions
Add camera and microphone to your allowed list by clicking Camera and Microphone separately. (Select allow only while using the app)
Go back to interview page, click "Record your response" and it should work now
