Susquehanna International Group Account Executive interview questions & guide 2026

The following questions are representative of the patterns observed in the SIG interview process. While your specific experience may vary, you should focus on developing a framework to address these core areas rather than attempting to memorize individual prompts.

Probability and Quantitative Reasoning

This category tests your ability to think clearly under pressure and apply mathematical concepts to real-world scenarios.

• If you roll two dice, what is the probability that the sum is seven?
• Can you explain Bayes’ Theorem and provide an example of how you would apply it to a decision-making process?

Preparation for SIG requires a disciplined approach that balances technical fluency with clear communication. You should treat your interview as an extension of the work you would perform on the desk: be precise, logical, and ready to defend your reasoning.

Role-related knowledge – You must demonstrate a functional understanding of financial markets, specifically options and probability theory. Interviewers look for candidates who can bridge the gap between abstract mathematical concepts and practical market applications.

Problem-solving ability – This is the core of the SIG evaluation. Whether you are solving a probability puzzle or addressing a hypothetical client issue, focus on showing your work, stating your assumptions, and maintaining a structured flow of logic.

Communication Clarity – Because you will be interacting with highly technical internal teams, your ability to articulate your thought process is as important as the answer itself. If a question is unclear, ask for clarification immediately rather than making assumptions.

The interview process at Susquehanna International Group is designed to assess both your technical aptitude and your cultural fit within a quantitative-first environment. You can expect a structured progression that begins with an online assessment, followed by a series of conversations designed to test your baseline knowledge and your potential for growth.

The pace is efficient, and you should be prepared for the level of rigor expected of a firm that values analytical excellence. The process is not merely about finding a candidate who knows the right answers, but about finding a candidate who thinks in the right way—methodically, logically, and with high intellectual integrity.

This timeline illustrates the progression from initial screening to the final desk-level interview. Use this to pace your preparation, ensuring you have refreshed your probability and options math before the initial assessment, and that you are ready to discuss your past projects in depth during the later behavioral rounds.

Quantitative Aptitude

SIG is a firm built on probability. Your ability to compute outcomes and understand risk is the primary filter for all candidates.

Be ready to go over:

• Probability Theory – Foundations of independent and dependent events.
• Expected Value – The ability to weigh outcomes against their likelihood of occurrence.

As an Account Executive, your day-to-day involves managing the flow of information between SIG and our external counterparts. You will be expected to monitor market activity, understand the nuances of the products we trade, and ensure that our clients receive the service and liquidity they require.

You will collaborate closely with traders and engineers, acting as a translator who ensures that market feedback is integrated into our internal processes. Success in this role means you are not just a point of contact, but a proactive partner who anticipates client needs and communicates them effectively to the desk.

A strong candidate for this position brings a combination of analytical discipline and interpersonal maturity.

• Must-have skills:
• Proficiency in probability and statistics.
• Strong mental math capabilities.
• Excellent verbal and written communication.
• A demonstrated interest in financial markets and trading.
• Nice-to-have skills:
• Experience with options pricing models.
• Prior experience in a client-facing role within finance.
• Familiarity with the competitive landscape of liquidity provision.

Q: How difficult are the probability questions? A: They are designed to test your fundamental understanding rather than advanced calculus; if you are comfortable with basic probability and Bayes' Theorem, you will be well-positioned for success.

Q: What is the most important trait for a successful candidate? A: Intellectual humility combined with a strong work ethic; we look for people who are eager to learn from our internal experts and are not afraid to admit when they don't know something.

Q: How long does the process take? A: While it can vary based on the specific desk and hiring needs, the process is generally efficient, moving from assessment to final rounds within a few weeks.

Q: Does the role require coding? A: While this is not a developer role, being comfortable with data and understanding the logic behind automated systems is highly beneficial.

• Practice mental math: You will likely be asked to solve problems without a calculator; practice regularly to keep your skills sharp.
• Understand the "Why": Don't just arrive at an answer; be prepared to explain the logic and the assumptions behind your conclusion.
• Be authentic: SIG values genuine interest and honesty; if you don't know an answer, focus on demonstrating your thought process and willingness to learn.
• Research the firm: Have a clear understanding of what SIG does as a liquidity provider and how that differs from a traditional brokerage.

The Account Executive role at Susquehanna International Group offers an unparalleled opportunity to work at the intersection of high-frequency trading and strategic relationship management.
