For me this was a three tier interview process. I met with the recruiters at a career fair and actually originally spoke to a representative of the Finance Division; however, the Operations Division representative overheard the conversation and told me I would be better suited for his division. He asked me to describe my work experience, and strangely enough he was right it aligned more with Operations than Finance. I gave him my resume' in hopes that he would give me some good news, he kind of shrugged and just told me to apply online if I was interested, and I assumed the opportunity was done.
About two weeks later I got a call from their SLC office, and he scheduled an interview for me to speak with someone in ops over the phone from their NYC offices. I applied for the internship online officially after the interview setup over the phone. Many people from my school received the phone interview. There was a miscommunication on the date of when I was supposed to speak with the interviewer, and I was shocked to get a call on Black Friday while I was shopping and not prepared but I still took the phone interview. It was 15 minutes, and the interviewer asked basic questions basically going over my resume and if I knew what operations did at Goldman. She was very pleasant to talk to and it ended being less an interview and her giving me advice and talking about her experience at Goldman.
About a week later I received an email congratulating me and inviting me to Super Day. Of the 10 people that made it to the phone interview from my school, I was the only that made it to Super Day (maybe because I also applied online helped because I also received the Congrats on the career login as well). Super Day was a round robin of two 30-minute interviews. I had a one-on-one interview where I was asked the why Goldman questions (why Goldman, what part of the division would you work, and how my experience would help at Goldman). The second interview was a two-on-one interview where the questions were all behavioral and situational (describe when you made a mistake, how do you address big problems, what does this word mean on your resume in simple terms, etc.) For me the experience was rather easy because I have quite a bit of work experience that I was easily able to apply to each question naturally. This interview went fairly well too. All three interviewers opened up to me and also basically provided me advice and insight into their experiences. Had the interview on Friday and got notified Wednesday.
