Who will be able to see my video?
Your recorded video will only be shared with the company you are applying to. Your data will not be shared with any third parties.
Do I get notified?/ Do I get a result?
How long it takes until you get contacted depends on the company you are applying to. The company you apply to also decides if they want to share the result with you. So it depends on the individual company rules and their application processes when you will be contacted and if you receive your results.
