We’ve seen a very consistent pattern in SIG’s Quantitative Analyst interviews: the firm cares less about polished storytelling and more about whether you can set up probability cleanly under pressure. Across candidate reports, the same themes keep resurfacing — Bayes, expected value, conditional probability, combinatorics, and brainteasers that look simple until the clock starts running. Multiple candidates noted that the hardest part was not the math itself, but the pace, with several saying they couldn’t finish every question even when the material felt familiar. That tells us SIG is screening for fast, accurate reasoning, not just raw quantitative background.
A second theme is that SIG wants evidence you understand the business context, not just the formulas. Candidates were asked why SIG, what makes its prop trading model distinctive, and even market-scenario questions that forced them to think like traders rather than pure academics. We also saw a few prompts that mixed finance intuition with math, like options, stock-pitch discussions, and questions about how markets react to events. The non-obvious signal here is that they seem to reward candidates who can move fluidly between abstract probability and practical trading logic.
Finally, our candidates report a fairly technical, sometimes stiff style of interaction. That means small mistakes matter: rushed arithmetic, vague explanations, or hand-wavy reasoning can hurt more than in a warmer process. The strongest candidates were the ones who answered crisply, stayed organized, and showed they had actually thought about SIG’s edge. In other words, speed plus precision is the real bar here, and the people who clear it usually sound effortless doing it.

The hardest part for me was the online math test, because it packed probability theory, basic logic, and word problems into a pretty short time window. It felt more time-pressured than the actual difficulty of the questions, so you had to move quickly and not get stuck on any one prompt. After that, the interview process was pretty straightforward on paper: I had an HR call first, then a round with two team members, and finally a chat with a director. The early conversation was mostly general background and motivation, and then they moved into 2–3 math questions centered on probability and expected value. Those were definitely tougher than the OA, but still manageable if you had reviewed the basics beforehand.
One question that stood out in the later conversation was about what their unique prop trading is, which made it feel like they wanted to see whether I had actually looked into the firm and understood what makes SIG different. The vibe, though, was not very warm to me. I had a hard time getting a personal feel for the people, and the interactions came across as pretty robotic. I wasn’t invited to any further interviews after the math test, and overall I didn’t get an offer. My main takeaway is that you should be ready for fast-paced probability and expected value questions, plus a basic understanding of SIG’s prop trading model and why it’s distinctive.
Prep tip from this candidate
Drill short-timed probability, expected value, basic logic, and word problems, since the OA was described as the main filter. Also be ready to explain what SIG’s unique prop trading is, since that came up in the later conversation.

Synthesized from candidate reports. Individual experiences may vary.
Candidates apply online through SIG’s portal or are contacted by a recruiter after applying. The first filter is typically a math-heavy online assessment, so the application stage mainly determines whether you advance to the timed screening.
This is the main early filter and is consistently described as fast-paced and probability-heavy. It usually includes around 15-20 questions covering probability, statistics, combinatorics, logic, expected value, and some finance or market scenarios, with tight timing and little room to revisit answers.
After the assessment, candidates typically speak with a recruiter or HR. This round is conversational but often includes technical probability questions, background review, motivation for finance, and questions about SIG specifically, such as why the firm or what makes its prop trading model unique.
Candidates then move to one or more interviews with team members, traders, or a quant engineer. These rounds focus on live probability, expected value, Bayes’ theorem, logic, and mental math, and may also include market intuition, finance questions, or light coding/ML concepts depending on the team.
Some candidates are asked to submit a video stock pitch, and others complete a take-home data science project, such as a modeling volatility assignment. This stage tests communication, market understanding, and the ability to present reasoning clearly outside of a live interview.
The final stage can be a director chat or a longer panel-style process with multiple interviews. Questions remain technical and often mix market scenarios with quantitative reasoning, while also checking fit, communication, and whether the candidate understands SIG’s trading model and culture.
