Goldman Sachs Investment Banking Associate Interview

Hi,

I have an upcoming 1st round Associate level full-time interview at Goldman Sachs coming up next week. The interview invite was extended to me outside of the normal on campus recruiting process through a referral from an Associate that I reached out to during the summer for an informational. I am at a top 3 target b-school where GS normally recruits, but based on what I have heard from sources they are trying to fill a few spots before OCR starts. I am interviewing with a specific industry group. I was hoping someone that has gone through the Associate level interview process can help shed some light as to the overall structure of the interviews. I am under the understanding that the interview process can be more prolonged in terms of number of rounds (up to 4) when interviewing individually as opposed to through OCR. Any insight with regards to the interview structure, typical behavioral questions, or any other information that might be relevant to MBA level hire would be much appreciated. Thanks
