Susquehanna International Group Operations Analyst interview questions & guide 2026

To succeed in the SIG hiring process, you must prepare for a blend of behavioral inquiries, probability puzzles, and analytical brain teasers. The questions are designed to evaluate how you structure your thoughts under pressure rather than whether you have memorized specific financial formulas.

Probability & Market Making

These questions assess your quantitative intuition, comfort with numbers, and understanding of expected value.

• What is the probability of rolling a sum of 9 with two standard six-sided dice?
• Let's play a game: I roll a die. If it lands on 6, I pay you $10. If it lands on any other number, you pay me $2. Would you play this game, and what is your expected value?

Preparing for an interview at Susquehanna International Group requires a shift in mindset compared to other corporate finance interviews. SIG values raw analytical talent, rational decision-making, and a passion for games of strategy over rote memorization of financial definitions.

To stand out, focus your preparation on the following key evaluation criteria:

Quantitative Aptitude – You must demonstrate strong mental math capabilities and a solid grasp of basic probability. Interviewers want to see that you can calculate expected values quickly and think probabilistically when assessing risk and reward.

Structured Problem-Solving – When presented with a complex brain teaser, your methodology matters far more than reaching the correct answer immediately. You should be prepared to explain your assumptions, break the problem into smaller parts, and talk through your logical steps out loud.

Decision-Making Under Uncertainty – SIG's culture is heavily influenced by game theory and poker. You will be evaluated on how you assess risk, how you handle situations with incomplete information, and whether you can remain calm and rational when your initial assumptions are challenged.

Operational Precision & Fit – Because an Operations Analyst handles critical post-trade data, you must showcase an exceptional eye for detail and a process-oriented mindset. You should be able to demonstrate how you prevent errors and why you are genuinely interested in supporting a fast-moving trading environment.

The interview process for the Operations Analyst position at SIG is rigorous, highly structured, and designed to test both your analytical capabilities and your behavioral alignment. Candidates can expect a multi-stage journey that transitions from high-level screening to intensive, hands-on problem-solving.

The process typically begins with an initial phone screen with a recruiter, which focuses on your background, resume, and motivation for joining SIG. This is followed by one or more technical and analytical phone or Zoom interviews. During these rounds, you will interact with traders or senior operations team members who will present you with probability questions, market-making scenarios, and brain teasers that require pen and paper to resolve.

The final stage is a comprehensive on-site or virtual superday. This final round is highly immersive, often lasting several hours. It typically includes a written brain teaser assessment, behavioral rotations with multiple operations team members, and a final conversation with a hiring manager or director. Throughout this entire journey, SIG maintains a strong focus on logical consistency, mental agility, and structured thinking.

The visual timeline above illustrates the typical progression of the SIG hiring process from application to final offer. Candidates should expect the technical and analytical testing to intensify during the middle rounds, culminating in a multi-faceted evaluation during the final onsite. Use this timeline to pace your study plan, ensuring you are fully prepared for the written and interactive puzzles before reaching the final stage.

To excel in the SIG interview process, you must understand the specific competencies being tested at each stage. The firm evaluates candidates across three primary dimensions.

Quantitative Reasoning & Probability

This area evaluates your comfort with numbers and your ability to apply mathematical logic to real-time scenarios. SIG views probability not just as an academic subject, but as a practical tool used daily to manage trading risk.

Be ready to go over:

• Expected Value Calculations – Determining the long-term average outcome of various games of chance or business decisions.
• Permutations and Combinations – Calculating the number of possible outcomes for complex, multi-stage events.
• Bayesian Probability – Updating the probability of a hypothesis as more proof or information becomes available.
• Advanced concepts (less common) – Conditional probability distributions, game theory matrices, and basic option pricing concepts.

Example questions or scenarios:

• "A bag contains 3 red marbles and 7 blue marbles. If you draw two marbles without replacement, what is the probability that both are red?"
• "You are offered a bet where you win $10 if a coin lands heads, but lose $8 if it lands tails. If you can play this game 100 times, what is your expected bankroll change?"

Brain Teasers & Analytical Problem Solving

Brain teasers are a staple of the SIG interview experience. They are designed to test your lateral thinking, your resilience when stuck, and how well you communicate your thought process under pressure.

Be ready to go over:

• Logical Deduction Puzzles – Using structured elimination to find a single correct solution from a set of constraints.
• Estimation & Fermi Problems – Making reasonable assumptions to estimate large, unknown quantities.
• Spatial and Temporal Math – Solving puzzles involving clocks, speeds, distances, and geometric configurations.

Example questions or scenarios:

• "You have a 3-gallon jug and a 5-gallon jug. How can you measure out exactly 4 gallons of water?"
• "Explain how you would estimate the total number of window washers currently working in the city of Philadelphia."

Behavioral Alignment & Decision Making

This evaluation area focuses on how you react to pressure, how you collaborate with highly analytical colleagues, and your overall interest in the operational side of trading.

Be ready to go over:

• Risk Mitigation Mindset – How you identify, escalate, and resolve operational errors before they impact the business.
• Handling Ambiguity – Your approach to completing tasks when instructions are vague or circumstances change rapidly.
• Detail Orientation – Demonstrating your systematic approach to checking your own work and maintaining flawless accuracy.

Example questions or scenarios:

• "Tell me about a time you made an error at work or school. How quickly did you spot it, and what steps did you take to rectify the situation?"
• "How do you handle working with team members who have highly analytical, direct, or 'robotic' communication styles?"

As an Operations Analyst at Susquehanna International Group, your daily responsibilities will center around supporting the trading floor and managing the lifecycle of financial transactions. You will operate in a high-stakes, real-time environment where accuracy and speed are paramount.

Your primary responsibilities will include:

• Trade Support and Reconciliation – Monitoring real-time trading activity to ensure all trades are captured accurately in internal systems and match external clearing house records.
• Position and Cash Management – Reconciling cash balances, stock positions, and derivative exposures daily to prevent overdrafts, settlement failures, or unauthorized market exposure.
• Risk and Compliance Monitoring – Identifying operational anomalies, trading limit breaches, or regulatory compliance discrepancies, and escalating them immediately to risk managers and trading desks.
• Process Automation and Optimization – Collaborating with software developers and systems engineers to automate manual operational workflows using Excel, SQL, or scripting languages.
• External Relationship Management – Acting as the primary point of contact for clearing firms, prime brokers, and exchanges to resolve settlement disputes and trade breaks.

In this role, you will not work in a vacuum. You will be seated close to the trading desks, experiencing the immediate impact of market volatility. When markets are active, your ability to quickly resolve trade discrepancies directly preserves the firm's profitability and operational integrity.

While you do not need deep programming knowledge, you will face rigorous testing on probability, mental math, and brain teasers.

Q: Do I need a background in finance or trading to get this job? A: No. SIG values raw analytical talent, logical reasoning, and a strong work ethic above specific financial knowledge.

Q: What is the company culture like for the operations team? A: The culture at SIG is highly meritocratic, logical, and fast-paced. Team members are direct, analytical, and supportive.

To maximize your chances of securing an offer as an Operations Analyst at SIG, keep these practical, firm-specific tips in mind during your preparation:

• Show Your Scratch Work – Always have a pen and paper ready for every interview round. When solving a brain teaser or probability question, write down your variables and walk the interviewer through your steps. This shows you are systematic and prevents simple mental math errors.
• Embrace the "Robotic" Communication Style – Some candidates find SIG interviewers to be highly direct, logical, and economical with their words. Do not take this personally; it is a reflection of the firm's highly objective, data-driven culture. Focus on delivering clear, structured, and factual answers.
• Prepare Your "Why SIG?" Story – SIG is distinct from traditional Wall Street investment banks. Make sure you can articulate why you want to work at a proprietary quantitative trading firm and how your skills align with their unique, game-theory-driven culture.
• Practice Market Making Games – Familiarize yourself with how to make a market on everyday estimations. Practice quoting a "bid" (the price you would buy at) and an "ask" (the price you would sell at) for random quantities, such as the height of the Empire State Building or the population of a city.

The Operations Analyst position at Susquehanna International Group offers an exceptional opportunity to build a career at the intersection of technology, finance, and game theory. By supporting the daily execution and risk management of one of the world's largest proprietary trading firms, you will develop a deep understanding of global markets and quantitative operations.

To succeed in this highly competitive interview process, focus your preparation on mastering basic probability, practicing lateral-thinking brain teasers, and refining your behavioral stories to highlight your structured decision-making and attention to detail.
