Interviewing at Susquehanna International Group
Susquehanna International Group (SIG) runs a screening pipeline that mixes strict online assessments with multi-round technical and behavioral evaluation. Across reported roles, the process culminates in a multi-round Superday that concludes the interview process, with several candidates reporting several hours of back-to-back evaluation.
What SIG tests shows up strongly in the topic coverage: Python and SQL, data cleaning and data quality checks, probability theory plus Bayes rule, and equity research. You should also expect foundational problem-solving in data structures and algorithms, plus applied reasoning around data manipulation and data standardization, and a heavy emphasis on probability and quantitative thinking in recruiter or early screens.
Timelines vary by path, but multiple reports describe the process as happening over a few weeks to a couple of months, with assessments that can be time-pressured and sometimes decisive early. Candidate reports show no offers in the aggregated sample, so treat this as a hard bar and focus on clean, step-by-step reasoning under time limits.
The most non-obvious part is that early steps are not just “fit” and “resume review,” they often include probability or math questions and strict filtering through the online assessment, so your ability to reason clearly fast matters before you even reach the Superday.

The interview process, end to end
5 rounds · based on 530 candidate reports- 1Online application
You submit your application online to begin the process. Some candidates report entering a broader program flow that still includes an online assessment and a behavioral component early.
- 2Online assessment and quantitative filter
You take a proctored coding challenge via an online platform, with 3 to 4 questions of varying difficulty, lasting 60 to 90 minutes. Multiple reports describe automated assessment as a strict filter, focusing on numerical reasoning, logical problem solving, and basic financial math, and some tests increase difficulty under time pressure.
- 3Recruiter phone screen
You have a recruiter conversation covering your resume, motivation for SIG, and basic behavioral questions. Reports also describe that this step can include a small set of probability or math questions, and that explanations are expected to be step-by-step.
- 4Technical interviews and/or structured or take-home exercises
You complete multiple technical interviews that evaluate analytical and quantitative abilities, and in some paths you also do a structured case study or a take-home case study. Topic coverage indicates heavy probability, Bayes rule, and probability-heavy reasoning, alongside Python and data cleaning themes for relevant roles.
- 5Superday
You reach a multi-round on-site or virtual final stage that concludes the interview process. Reports describe multiple rounds with written brain teaser assessment and behavioral rotations, and others describe final-stage assessment including management-level evaluation and rigorous technical design or scenario questions.

What separates offers from rejections
Patterns from candidates who got offers, and the mistakes that most often sink a loop.
Do this
- Practice end-to-end probability reasoning, including Bayes rule and expected-value style logic, and make your steps explicit. Multiple reports and the topic list show probability as a core theme in both assessments and recruiter or technical screens.
- Be ready to do data cleaning and data quality checks with Python, plus data manipulation and data standardization concepts. The topic coverage includes all of these at very high percentiles.
- Prepare for Python plus SQL together, not separately. Python and SQL are both near the top of the topic distribution, so be comfortable switching between them.
- For the final stage, expect multiple back-to-back rounds that include behavioral and technical components. Use structured explanations of tradeoffs and keep your communication clear, because reports describe rigorous technical evaluation alongside behavioral rotation.
Avoid this
- Do not assume the recruiter call is purely behavioral. Reports describe recruiter screens that include probability questions or basic financial math, so show quantitative thinking readiness early.
- Do not rely on calculators or vague reasoning for math or probability questions. One report explicitly notes no calculator reliance and that you must explain reasoning step by step.
- Do not treat time limits as optional. The online assessments are described as time-pressured, with strict filtering, and difficulty is reported as increasing across the test.
- Do not coast after early rounds. Reports describe paths that end quickly after HR or early screening, and others that escalate into deeper math and a final-stage exercise or Superday.
Susquehanna International Group interview FAQ
Answered from real candidate and workplace dataHow hard is the interview loop here?
In the candidate report sample, difficulty is mostly medium (55.2%) and hard (28.8%), with a smaller very hard share (3.6%) and easy share (12.4%). Reports repeatedly describe time pressure, increasing difficulty in the online assessment, and later rounds that go beyond basic problem solving.
How long does the process take?
Candidate reports describe timelines ranging from a few weeks to a couple of months, depending on the path. Some loops end early, while others continue into deeper math discussions and then a final-stage onsite or exercise.
What should I prioritize studying for the actual questions they ask?
Prioritize Python and SQL, data cleaning, probability theory, Bayes rule, and data structures and algorithms. The extracted topic coverage also puts equity research at the top level, and includes data manipulation, data standardization, and data quality checks with high prominence.
Is there a case study or take-home component?
Yes, some paths include a structured case study or a take-home case study, including an Excel-based technical assessment in at least one reported path. Reports also describe a final-stage exercise after interviews for certain candidates.
Do people get offers from this process?
In the aggregated candidate reports you provided, the offer rate is 0.0%. That means in this dataset no candidate reported receiving an offer, so you should assume the bar is high.
If I do not pass, can I re-apply?
Your provided data does not include any policy or guidance on re-application. The only consistent signal from reports is that early screens can end the process quickly, so you would need feedback to know how to improve for any future try.
