I applied through college or university. I interviewed at Discover
Interview
I had 2 interviews on my university campus. One was behavioral, the other was a case. Both were very laid back. About a month later I was called in for an interview on their campus in Riverwoods. There were 3 behavioral interviews, a group interview, and a group case.
Interview questions [1]
Question 1
Nothing was particularly difficult. They did not ask any high level finance questions. There is very little you can do to prepare for this interview.
Applied through university, interviewed on campus, contacted a few weeks later for interview at HQ, dinner the night before, they put us up in a hotel, three personal interviews (behavioral, leadership, problem solving), group interview, group case presentation, very nice people and welcoming environment, no follow up email to say if you didn't get the position
