The way I got the interview was through a campus informational session. Use that time to ask as many questions about the company as possible. Also, after the session meet EVERY representative there and speak with them on their journey throughout the company. If they're holding on campus interviews, these will probably be the same people interviewing you in the coming days. I was able to sign up for the interview at the informational. The interview was set up more as a conversation. There weren't that many questions, however, the person spent a lot of time giving me advice for the future, even outside of interview tips.
