J.P. Morgan Data Mining Analyst interview questions

I'm a computer science major at a major US university, and came across this job at a career fair for people in my field. I went up to the Chase booth and told them I was looking for a software development position. The recruiter told me they weren't really hiring for that, but needed skilled people for analytics jobs. I just changed majors, and I'm looking for whatever experience I could, so I said I'd be interested. They were looking for full-time people, but when I told him I was looking for an internship, he said that for the right candidate, something could be arranged. I interviewed with them the next day, when a lot of employers at the fair were doing next-day interviews. The interview process was a little more intense than I expected. The first interview was mostly behavioral, tell me about yourself, etc. The second interview was a 3 part case interview with three questions. If you have some experience with case interviews, it shouldn't be too bad. First question was something like "how many gas stations are there in the US?", the next one was a similar logic question, and the third one was a question about Chase's business model and my opinion. They basically told me that they were only looking for full-time hires, but said that they were impressed with me and would talk to their internship team about whether they can find a spot for me. I still haven't heard back from them, but am really looking for a software dev position, so I would probably decline unless the offer was really great.
