The process took 1 week. I interviewed at Group One Trading (San Francisco, CA) in Jun 2009
Interview
First phone interviewer asked me to read a book about how traders are bad people. The second phone interviewer asked what I thought of the book. I'm not sure what I was supposed to say -- I disagree? I understand that traders are bad people and I still want the job? The book basically talked me out of wanting this position.
Interview questions [1]
Question 1
Find the coin that weighs more (8 coins, using a balance)
Series of zoom calls. Behaviorals and math. Interviews have two people. One watching how you react. Process is a little longer than most firms but also depends on how quickly you get things scheduled
Did two rounds of interviews, first round had some technical questions, the second round was completely fit / understanding questions. It was overall very relaxed, and I was told a week after the second interview that I got the intern position.
Interview questions [2]
Question 1
What is the difference between prop trading and other forms of trading?
I applied through an employee referral. The process took 2 weeks. I interviewed at Group One Trading (Chicago, IL) in Mar 2013
Interview
First interview is analytical, second is more personality based. Be sure to prepare your mental math skills. If you don't know the answer try to work through it out loud, they are more interested in your thought process. Don't be afraid to ask questions or clarification. They will ask why you are interested in trading in general. Be sure to emphasize a competitive nature and ability to learn.
I had one interview over the phone and two in person.
