The interview was mainly behavioral questions. The first round was at my school with a senior manager. The second round interview was with three partners of the firm. There were no tricky questions just the typical "Tell me about yourself..." and "Discuss a time you demonstrated leadership"...etc. In order to get a first round interview, I would say that your resume will play the most significant role, specifically your GPA (above 3.5) and to get a second round interview depends on both your experience level and your personality. The actual offer seemed to be based completely on personality and how much they liked you, since the partners cared a lot less about looking at your resume and more about just having a conversation with you. I would just recommend that you sell yourself but do it discretely...and just be yourself. Don't try to be someone you're not and definitely try to show that your a social, outgoing person that could be a fun person to work with.
