If you have to record a video response in your assessment, you will have the opportunity to practice a video response.
You will first be asked to verify that your camera and microphone are working as expected by recording a short video. You will then be able to play it back and check the quality of your video and audio. You can record this video several times until you can see and hear yourself well.
In some cases, you will also be asked to respond to a non-assessed, timed question, that follows a more similar format to the questions you will be asked later on in the assessment. The purpose of this second question is to better prepare you for the assessment.
