I applied on my college's job site (no cover letter, just a resume), and was contacted after the end of the resume drop deadline for an interview and a pre-interview mixer. Mixer was quite long - about two hours - but it was a great opportunity to meet the interviewers ahead of time and learn about them and the company without the pressure of the interview format. Interview was two half hour interviews with two people each, who were from different seniority levels of the marketing arm. Very interesting questions that were split between asking about experiences and marketing specific questions, but very doable even though it was my first marketing interview (mostly assessing what you would do in a specific situation, trends in general that you see happening). Overall a really pleasant experience that almost didn't feel like an interview.
