The interview comes after the applicant has passed the written exam. It is quite structured and features one-on-one and group settings. It really depends on who you get as interviewers and how well you gel with the people who are interviewing the same day you are. It isn't easy but I had fun during it.

Interview is an all-day, three part process. The first part assesses how you work in a group. The second part assesses how well you can reason and write a memo, and the third part is a straight up interview designed to assess cultural fit.
