PEAK6 Interview Questions
& Process

First there was an online assessment, then I spoke with a recruiter, followed by a two-part interview that covered both behavioral and technical aspects. After that, I had a super day in the Chicago office. It wasn't too hard, but I didn't move on after the two online parts.

My first video interview got ghosted, which was rough because I value punctuality. Usually, if a candidate misses an interview, they're out, but HR acted like it was normal and didn't really apologize, though they moved me forward. The next interview was with a teammate who's an escalation point. We clicked, and he seemed happy with my answers, so I moved on. Then I talked to a manager, and honestly, I barely said anything. He was shocked by my experience and passed me to the next round without much discussion. The final round had two back-to-back interviews with upper management. I talked about wanting to learn, grow, and evolve in the role, which was tough since I couldn't really show that in the earlier interviews, especially after being ghosted initially. They rejected me, saying my interests couldn't be met. I figured this out because HR relisted the job on LinkedIn just two days later. I emailed HR for an update, and they took a while to reply. It seems like whoever takes this job shouldn't expect career growth or advancement, as it's more like career regression unless that's your thing. But hey, they were upfront about it, which I appreciate.

The interview process started with an online assessment which was a slight variation on questions others have encountered. This was followed by a video interview where we discussed my previous work and some fundamental technical topics. The final stage was a virtual on-site, which included five interviews: one focused on coding, another on system design, a third on technical (non-coding) aspects, and the remaining interviews were geared towards behavioral and fit assessments. The coding round specifically involved a problem related to the trading industry. Throughout the process, the people I interacted with were very friendly and seemed genuinely happy to be part of PEAK6.

I was referred to Peak6 by an employee and was really excited about the opportunity. The first phone screen happened quickly, followed by a Zoom interview with the hiring manager. The hiring manager seemed to like my background and said they'd update me on next steps. After a week with no follow-up, I emailed them. A week later, still no response, so I had my internal reference ask for an update. I got an immediate call saying I'd hear back by end of day. No response from HR, but the next morning I got a vague email saying I was being passed to a different recruiter. I asked for clarification, but again, no response and I had to follow up again. HR then called to say the hiring manager isn't ready to fill the position, understanding my frustration but stating their hands are tied. I'm posting this because if Peak6 wants to make a good impression on referred candidates, they should formalize their process. It was a frustrating few weeks, and what looked like a great opportunity now seems like a dodged bullet due to their spotty communication.
