The S&T Analyst interviews start as an informal dinner the night before interviews. This is a great opportunity to meet your potential interviewer and get to know more about the firm and culture. The first round interview is highly dependent on your interviewer, but it's safe to say you'll be asked a lot about your resume/work experience & interests along with your motivation for applying to the job. There will be some market related questions and some simple math or brainteasers to judge your quantitative ability. The second round superday was similar, in that it was 4 30 mins interviews that were fairly similar. Everyone asks you about you, your past experience, your interests, your knowledge of markets and what you expect to learn/do. Everyone I came across was very positive and nice, but not easy or complacent.

Very Quantitative interview. Asked Brain Teasers, current market knowledge and about current interest rates. Waws interviewed by analysts first then the MD. Made it to superday and was interviewed all day long.
