An on campus interview by an alum, which was relaxed and surprisingly fast. Asked why I want to work in the finance industry, how does JPMC make money, which threw me off a little. Then went over my resume. Was asked a brain teaser at the end, which wasn't incredibly difficult. Heard back that I got the internship only 2 weeks later.
This was my first on campus interview, so I had no idea what to expect and was quite surprised I got an offer.
