Capital One Business Analyst Power Day

So I have worked my way through the steps of the Capital One interview process and received an invite to their power-day for the Business Analyst Role. I keep hearing that the case interviews will be similar to that of consulting. At the same time, I'm being told that the Capital One cases are much more quantitate and interviewer led. 

I have no prior consulting prep experience, but I want to make sure I prepare for this power-day since it's probably the best opportunity I'll have lined up. I just picked up some case book pdfs to go through, but I'm getting the idea that this wont be similar to the Capital One case. Can anyone who has interviewed for this before provide any insight please? What should I be focusing on and how can I prepare to do my best? Also, from what you have heard, is getting an offer relatively difficult? Thanks for all the help!
