Once you're in the interview and have recorded an answer, you will see the following buttons so you can choose to Re-record or submit your answer by selecting Done:

Please note: certain interviews have a limited number of retakes - if this is the case, be sure to check before you answer it. If a question has a limited number of retakes you will see this below the Done button.

We would recommend that you practice to get comfortable with the process before you start filming.  

Once your video interview has been submitted you will need to contact the organisation who created the interview directly if you wish to retake the interview entirely.
