Five to six candidates are grouped together and asked to develop a presentation around a specific prompt, which invited applicants are sent in advance of the interview. Afterward the group exercise, candidates have about 10 minutes one on one with an interviewer-usually a trained second-year student but sometimes a member of the adcom. You're typically given one minute to introduce yourself, and the sequence lasts in total 35 minutes, when the team of candidates comes up with a topic and presentation model that is ultimately shared with the adcom observer.
