I'm currently in the interview process with the Chicago location. I passed the first numerical test pretty easily (~65 out of 80) and just took the behavioral interview earlier today. I'm nervous to find out if I passed the behavioral round... could anyone let me know how long they usually take to get back to you if you made it to the next round? Also, what are the chances like of getting hired if you've passed the first two rounds?
Had a friend who worked there years ago. From what i hear its very cut throat, one anecdote I remember hearing is that grads are told they need to go socialize with other traders at other places specifically to gain insights into what others are doing.
Also the arithmetic test for their interviews is quite brutal.
