The process took 1 day. I interviewed at Susquehanna International Group (Philadelphia, PA) in Oct 2011
Interview
I managed to visit the Philadelphia office last year. Brilliant office, great academic environment, nice people. Poker is heavily emphasized in training traders.
Application was straightforward.
Interviewer was pleasant and casual. Started with behavioral questions, then walking through resume to check your vital signs, then conditional probability questions. The probability questions started easy and got progressively harder until some fairly complex ones on pricing games.
Interview questions [1]
Question 1
I have 10 cards face-down numbered 1 through 10. We play a game in which you choose a card and I give you the corresponding dollar amount.
a) What is the fair price of this game?
b) Now, after picking a card you can either take the dollar value on the card or $3.50. Also, cards worth less than 5 are now valued at $0. What is the maximum price you are now willing to pay for the game?
