I applied through university. The process took 2 weeks. I interviewed at Susquehanna International Group
Interview
I had to contact HR for an expedited interview because of an impending offer. I received a phone call a few days later for a quick interview. It consisted of a very brief overview of my experience/resume and a simple expected value math problem.
Interview questions [1]
Question 1
We're playing a game. Cards numbered from 1-10 are placed in a hat. Whatever card is drawn is the paid out amount. How much should I charge you to play this game (i.e. fair price)? If you can redraw by placing the first card back into the hat, what is the new price?
The fit questions were as expected, and the game theory question was a simple iterative question. The culture seems interesting however as it is a trading office they have no cafeteria and you must eat at your desk. The culture is still very team based as everyone works in smaller trading pods focused on different sectors.
I applied through university. The process took 3 weeks. I interviewed at Susquehanna International Group (Bala Cynwyd, PA) in Mar 2013
Interview
Applied via University's career network and on SIG's website. Was contacted by HR in about 2 weeks. Interview was a phone interview and consisted of basic behavioral questions and basic questions tailored at getting to know the candidate's interests.
The end of the interview consisted of a somewhat difficult statistical question.
Overall, the interview process went well. The interviewer was friendly and answered every question that was asked. Response was very quick, was notified within 4 days of the interview.
