I've also had the annoyance of being 'interviewed' using this ProctorU method. They have this 'feature' where you are not allowed to navigate away from the webpage that has the test, and if you do, it 'blocks' you from doing anything until you message the proctor and have them reset it for you. Except, in my case, this damn thing kept blocking up every few minutes, and I had no idea why. Contacting the proctor, having them diagnose it, and getting them to reset it, wasted a few minutes every time. I finally realized what the 'problem' was. It was firing the 'navigate away' event every time the mouse went outside the boundary of the page. Since I often play with my mouse, moving it around the screen, it would block me any time the pointer left the page. I eventually figured it out, but it took me 3–4 block-contact-reset cycles. All in all, a pretty annoying experience.
