Summer Analyst IMD

Went to an oncampus Info Session, I'm a 3rd year at a target school in CA. Info Session had all 4 major divisions at GS, about 30 total GS folks came from analyst to MDs.Applied online.
First round interview at campus career center, interviewed with Associate and VP from Investment Management Division. VP did most of the talking, interview was mostly fit questions, slight technical questions probably due to a previous IB internship. Mostly behavioral stuff and others, some questions were: tell me about a class you struggled with, what does an IMD analyst do?(to which I responded I do not know) Why banking? Why do you think you could do banking?
Associate was quite nice, and I was familiar with him from an earlier conversation, he was the good cop and VP was trying to get me off balance, both were very nice and polite.
The next morning I received a call that I have a superday invite, without giving me the date, a week later I received the actual details for the superday. Superday will be held in SF office, 4 hour duration, if necessary expenses would've been paid, and parking validated. Goldman provides an onsite contact to help with figuring out the building.
