Goldman Sachs Developer interview questions

The interview starts with 2 coder pad sessions, questions are straight forward. Interviewers are nice. Then followed by 2 face-to-face. No behavioral questions, purely on data structure and paper work programming, very tough questions. Even interviewers takes long time to realize your solution is working.

Positive experience with general behavior questions. Asked about general machine learning background and what related project I have done. What machine learning algorithm I have learned and which one is my favorite.
