Interview at Goldman Sachs

I was contacted by a recruiter from Goldman Sachs Marcus team and asked if I can interview there. I am a developer and I do a lot of market analysis as hobby. She found this out and asked if I can interview with them. But I have no idea how their interviews will be. Can anyone share their interview experiences with this team? I would Iike to know what kind of interviews they have ? Brain teasers? Google hardness level? Leetcode medium/hard/easy level? Any information would help. Thank you. Yoe: 3yrs
