I applied online. The process took 2 weeks. I interviewed at PEAK6 (Chicago, IL) in Sep 2020
Interview
They sent me a logical test which was sort of difficult (mostly it was about finding patterns in figures, numbers, etc). Guess I did well enough so they invited me for 2 interviews: the first more technical and the second behavioral; 30 mins each.
Interview questions [1]
Question 1
They asked me to drop my pen and shot me a bunch of math questions for 4 minutes. The objective was to answer as many as possible within the time frame. Some were pretty basic some were more complicated, for example: tell me the sqr root of 657 to the nearest decimal.

Interview
First interview was a phone. This one is easy--- they just ask you to rehash your resume. Then they invite you to interview in person downtown. The second interview was a two-person panel where they give you math/logic questions. Have your probability skills handy. They need you to solve things at the top of your head.

In a Russian roulette, 6 bullet chambers, and one bullet... One trigger pulled, no bullet. What is the probability of having a bullet in the next chamber?
