Real, anonymous reports from people who interviewed for Quantitative Analyst at Susquehanna International Group, newest first and distilled into what to expect across the loop.
My process leaned hard into the kind of OA-style difficulty where runtime and optimization mattered as much as correctness. I took an OA and then worked through a general coding assessment that required me to implement classic data-structure and algorithm tasks—things like hash map handling, binary search, queues, and heap operations. The difficulty increased across the set, and I remember needing to focus on the early problems quickly so I had enough time for the late ones.
My timeline was straightforward: I encountered an OA first and then moved into quick interviews that covered a mix of probability and coding/problem-solving. The technical parts weren’t described as impossibly hard, but they could be a bit tricky, and the real challenge was staying consistent rather than getting stuck on a single question.
The interview process begins with a timed online assessment focused primarily on probability, logic, and combinatorics, which increases in difficulty. Candidates should prepare for a variety of probability-based questions and manage their time effectively to complete the assessment successfully.
Following the OA, candidates participate in technical interviews that emphasize problem-solving, particularly in probability and expected value. Interviewers expect candidates to articulate their thought processes clearly while solving problems under time pressure.
Initial HR or recruiter calls focus on behavioral questions and fit for the role, often feeling conversational. Candidates should be prepared to discuss their motivations for transitioning into quantitative finance and their background.
Candidates report a consistent theme of increasing difficulty throughout the interview process, with a strong emphasis on maintaining composure and accuracy under time constraints. The pressure to perform well escalates, particularly in later rounds.
Candidates often experience a lack of feedback and communication following assessments and interviews, which can lead to frustration. It's important to be prepared for the possibility of limited updates throughout the process.
In some cases, the process culminates in a superday or multiple back-to-back interviews, which can include a mix of technical and behavioral assessments. Candidates should be ready for a rigorous evaluation across various formats in a condensed timeframe.
