Just wanted to give a bit of advice on the video questions....
I had some technical problems that ended up delaying my video my about an hour. You can log-in and test out the system at a time prior to when you want to complete the actual interview. I ended up only having one window to do both, and it was a little bit stressful trying to resolve these issues while at the same time remaining calm for the questions. I'd recommend logging in ahead of time just to make sure your webcam/audio are working properly with the system...especially if you're going to be cutting it close with the deadline.
My feedback for the questions mirrors what others have said. They cut you off at 90 seconds sharp, so make sure to tie up loose ends prior to the final three seconds. Otherwise, based on what I could see from the practice questions, it will catch you mid-word.
Good luck everyone!
