Last round of interviews

I need some help. I have a last round of interviews with a bank in the South. It is an analyst position with the Treasury department. The bank is paying for my flight and accomodation during the interview. I will like to know what is my probability of landing this job. I am really interested to be a part of this department. I spoke to the head of that department during the second interview. He is a very cool and laid back guy. He made me feel completely at ease, and I feel like he is someone who I will have a great work relationship with.

What should I expect during the interview at the corporate headquaters? It is an asset/liability position.
