Superday Help Needed

I have a superday with Deutsche Bank Corporate Banking Coverage. What should I prepare for them to ask me?

So far I've prepped for: why corporate banking vs. IB, what makes a company credit worthy, different types of debt. I also have studied the 400 questions guide since I'm recruiting IB as well. What else should I know?

Also, could someone give me more insight as to what the group does? From what I know, it lends from its balance sheet to $2B+ companies. I also heard something about how it covers companies, so for a given company, it will be involved with all the deals done for that company.
