I was contacted by JPMorgan via e-mail several weeks after my first interview on campus. This interview was an on site interview called Interview Super Day. It consisted of two interviews and a presentation. The interviews were very casual. They have sheets of paper with standard questions on it and the interviewer will choose a couple. In the email it was asked that I prepare a technical presentation that was 10 to 15 minutes about any technical project or idea you have worked on. I was expecting it to be a very formal presentation where I would deliver it in front of a panel and no one would speak until it was finished. Rather, I sat down one on one with the interviewer and it was more of a mix of a presentation and questions about the subject - much more casual than I anticipated.
