FO or BO? Wells Fargo "Finance" Internship?

Applied a while back for a random internship at WF called the "Finance" internship. I did a hirevue a few weeks ago and was just invited to a superday in about two weeks (post WF IB placement?). The description for the role is incredibly vague and it's unclear what the role actually is. Below is the Business overview on the job app:

"Finance is comprised of the following groups: Commercial Banking Finance, Consumer and Small Business Banking Finance, Consumer Lending Finance, Controllers Division, COO Finance, Corporate and Investment Banking Finance, Corporate Finance, Investment Portfolio, Investor Relations, Technology Finance, Treasury, and Wealth & Investment Management Finance."

I assume this means I could be placed in any of these roles, but I really don't know. It could also be a BO "operations" role maybe? I like the idea that I could be placed in IB (even if shitty location) but is that really feasible? 

Here's the description for the "Finance" program, this is not the job: application: https://www.wellsfargojobs.com/en/university-prog…

I would hugely appreciate if anyone could shed some light on this, I'm not sure how to prepare for this interview, and I'm unable to network to learn more about it because no one has "finance intern" on their linkedin. Any and all advice is appreciated. Thanks.
