The worst was an online app my friend was taking and after 30 minutes, it got to a point where she had to do one of those surveys but it would launch it in a separate window, which seemed fine, only it was supposed to close and return to the main site afterward and it never did, it just glitched out. So when she tried to continue the app, it wouldn't let her because it said she didn't complete the survey and when she tried to launch the survey again, it said it couldn't because the survey was already completed
She even had me log in to her stuff to give it a shot on my computer in case it was just something glitchy with hers but nope, same deal. Best part was that she called the company and HR trying to get through to someone who could help so that she could finish the app or if she could just send her info ahead and no one even knew who to direct her to lol This was a big retail company, something like Macy's. She gave up and moved on.
