Yes, you will have the ability to perform a practice question, which can be reviewed to ensure lighting and sound levels are correct. We strongly recommend you try this out before commencing the interview for real. The practice question is for you only, it is not uploaded as part of your video interview.
Please note however if you are running an older version of Android, in particular Kit Kat (versions 4.4.x), playback is not available. You can of course retry.
