I applied through an employee referral. I interviewed at PEAK6
Interview
After filling out an application online, you have about a week to fill out two different online exams, in a sense. One is a more traditional personality survey. The other consists of short probability questions; there are only ten and you have three minutes to answer each. Not being great at timed tests I was panicking the whole time and got the answer consistently after three minutes. They then will contact you if they want you to do a phone interview and set up a time. Phone interview covers basic questions and explains the job more in depth.
Interview questions [1]
Question 1
How did you overcome difficulty in a group setting?
First part is OA with logic Qs brain teasers and probability. The next round is the behavior / trader interview, with standard strategy / probability questions. I have scored 60+ on 80 in 8 and zetamac, but I cannot do *oral* mental math easily, without being about to see the numbers in front of me so I did not do well on this portion. They are very courteous about responding quickly tho.
1st round interview: online timed quantitative assessment
2nd round interview: virtual behavioral interview and technical interview
Final round interview: superday with many rounds of interviews including behavioral interviews, technical interviews, and a case study
I applied online. The process took 2 weeks. I interviewed at PEAK6 in Aug 2022
Interview
Was sent an OA, basically a raven's matrices test with some math questions sprinkled in. Literally just an IQ test. Took them 2 weeks to respond to me with a rejection email
