Very normal interview process, asked you to introduce yourself, and some common interview questions. Then had a 20-min test including five pages. Most of the problems in the test are very fundamental probability problems. Some questions about the financial market on the first page as well. On the last page is a personality test.

The process was fair, and the interviewer was kind and helpful. Great view from their NY office. The interview took about 2 hours, with only one interviewer. Paper test plus behavioural questions, and technical questions about trading. Be prepared for some math questions.
