Non-Target Meetings Help

Hey guys, I was wondering if I could receive some input on my situation and the steps I could take to better my situation.

I attend a non-target, and have a 3.65 overall GPA, but a 4.0 in two majors, accounting and finance. I have done well in all of my business classes, but started in a major upon the recommendation of my parents and wasn't really interested it, which is why my GPA is lower than my major. For the past year I haven't receive a GPA of less than 4.0 in my upper level accounting, finance and economics courses. I am entering my senior year of college, and will be expecting to graduate next spring.

Over the past winter, I had an internship in Audit with one of the Big 4 and did phenomenally (at least from the perspective of my reviewers) I received a job offer. To prepare myself, I had mostly taken accounting courses and was postponing my finance courses until the end of my degree (poor choice, in retrospect, I didn't need to know half of what I did for what I did on my internship). I hadn't really made a clear assessment of my options. Since getting into finance course-work and doing lots of research on the field(through interview guides(Vault, Breaking Into Wall Street, etc), school's Bloomberg Terminals (this is for deal information and League Tables) and practice interviews with faculty at the school who have worked on Wall Street. Further, like I assume most do, I read The WSJ & Economist (daily and weekly).

Given all of this, I would think I have no shot on getting into an IBD. My one advantage is that my father is the president of a very large private company that uses the services of BB's and MM's in Chicago and his staff has contacts with individuals at the BB's and MM's in Chicago. The VP of Finance for my father's company has reached out for me and it is looking like I may have the opportunity to have meetings with MD's or potentially even more senior bankers (as far as responsibilities, not titles, Heads of Coverage Groups/Heads of Product Groups, etc) in Chicago.

What input or suggestions do you have for me when I meet with these bankers, should I treat it similar to a very informal meeting (I was thinking I would wear business formal regardless), or should I expect an interview? Will I still have an incredibly hard time in trying secure a FT position?
