After submitting my resume at a career fair, I was contacted for an on-campus interview within a week. This turned into a skype interview due to convenience. This first interview was purely a fit interview, talking about company culture, asking about my experiences and skills. The interviewer indicated that I would probably be moving on to the next round, which was confirmed by an email from Putnam within a week. I was invited to Boston for 4 interviews over the course of 3 hours. All 4 were fit interviews. One interviewer was an HR honcho, the other three were coders. One was really quiet, one was a very friendly woman, and the last was a no-nonsense, get-it-done kind of friendly. This last interviewer asked a couple of technical questions, but they weren't particularly difficult. See below. About three weeks later, I received my final answer.
