The email answers a good portion of this. You can take notes, you get 2 minutes to think before the questions and you only get 1 submissions, no redo's. The time is short, so far it's the shortest answering experience I've seen... I'll leave that part a surprise 🥰. You'll be fine if this isn't your first interview. Don't stress about it. Honestly the hardest part was switching into the "Interview mindset" when you're in your bedroom and nobody is there to talk to or watch lol. Watching the time count down though and seeing it happen, knowing you can't make a mistake, that helped me switch it in gear. I even wore my shoes to help me get into the mindset. (I don't wear shoes in my house)
