The process took 1 day. I interviewed at DRW (Chicago, IL) in Oct 2009
Interview
The first 15 minutes of the interview were strictly behavioral questions about my resume, my accomplishments, interests, etc. The later half were a set of math/logic questions, which were common brainteasers such as 2 digit multiplications, angles of analog clock, expected value and such. Interviewer was very nice, chill guy and would offer help if I got stuck somewhere.
I applied online. The process took 6 months. I interviewed at DRW (London, England) in Feb 2025
Interview
The process lasted a total of 6 months, with a total of 7 interviews, a mix of technical interviews and tests. I had 2 'final' interviews.
The whole time I was kept in the dark about the status of my application and reasons for delay, despite constantly requesting this information. I asked to have a call, only to be told that the role isn't going to be filled and that they've lost the headcount. Terrible treatment on the back of a terribly managed process.

Interview
The phone interview was primarily based on personality and fit questions, with a couple of brainteasers included near the end. There were almost no technical questions included, aside from the online mental math quiz.
Interview questions [1]
Question 1
If I gave you $100,000, what would you do with it? How many quarters would it take to fill a 20x20x10 foot room?
HR was very helpful, Interview time was arranged by email. Interviewer did not make you feel at ease but it is completely random who you get. A relatively important issue is that the call you through speakerphone and the sound coming through is somewhat muffled.
