8 hours will more than likely be the entire interview process assuming you pass the credit and core values assessment.
You have to be current on all bills if you're not getn on a payment plan and have a letter from the creditors.
Core values is testing your integrity so you want to keep that in mind. I would take a lunch I didn't to my interview and should have because it did take all day lol. The actual interview lasted maybe 20 mins. You will go over every charge or conviction ever. Disclose everything no matter how small or insignificant you might think it is even if it's embarrassing. Again it's an honesty and integrity thing.
