Potentially good opportunity

I recently graduated college from a non-target school and with a degree in International Affairs so despite always being interested in this field, I considered myself screwed when it came to anything in this world. However, I recently learned that the person that lived across the street from me while growing up is a SVP at a mid-sized bank and specializes in emerging markets of all things. I reached out to him and he seemed excited and invited me down to the office to come “check everything out”. Would someone like this even have hiring power? I currently work in finance and studied a lot of international economy and business in college. I plan on networking my ass off and trying not to come off as a spaz. I’ve been obsessing over this meeting and have gone over my resume probably 100 times now. I feel like this is my best shot at networking my way into this field. Do I even need to be worrying about it this much? Has anyone had any experience with something like this?
