Four interviews of a half hour each, with each one being 1:1. Interviewers were nice and easy to talk to for the most part. Mostly asked for explanations of my resume and previous internship. Sometimes asked about career goals or why I wanted to work for Goldman Sachs. A few of them said obscure things like "tell me about yourself." They seemed to like when I asked THEM questions as well, about the firm and about the division.
