I've only had the digital interview, in which you record yourself answering questions. You can do a few practice questions (which aren't recorded) so that you can get the hang of it, but even after doing 2 or 3 of those, I choked on the first recorded question. There were about 8 questions in total, 5/6 of which were recorded. The rest were just multiple choice. As far as the recorded questions, you get 30 seconds to prep for each one after the question is asked, and your response can be up to 3 minutes long.
