I met a recruiter at a Career Fair at my university. Had a nice conversation and left my resume. Got a call within a week or two and was invited to a 1:1 in-depth interview with the College Recruiter. There were 3 interviews including the first 1:1 in-depth interview, 1:1 motivation interview, and self-created presentation. Questions were intended to ask my motivation to work at Northwestern Mutual and evaluate the track record of success. Considering the nature of the primary duties of a representative, you might want to indicate that you possess the sales skill and interpersonal skills.

There were four or five interviews, if you count the meeting with my future mentor. There were also a few personality assessments. Lots of paperwork. The finance industry is tightly regulated.
