The first interview took place on my university campus. It consisted of a 1:1 interview with a current employee of the firm. It's a relatively new firm branched off of JP Morgan. The interview consisted of a resume analysis, future goals, and a few brain teasers. They asked me if I read the wall street journal, the economists..etc.
The final round took place in their New York office. Went through a series of interviews consisting of finance questions, statistics, brain teasers, probability related questions, and trading strategies. Definitely a stressful interview. They didn't hire anyone in the end because their "funding in January never came in."
