I am guessing both AWS and GCP take time to rewatch your remote proctoring video to ensure there has been no cheating. Kind of invalidates the presence of the proctor, but I much prefer GCP's way of providing proof of preliminary results first and then taking their own sweet time to validate your result, over AWS's method of causing unnecessary anxiety to test takers who have no proof of their result, even if it's for a few days. Imagine the amount of effort and money put into this certification, only to cost you more anxiety and stress after successfully completing it.
