I applied online. I interviewed at Susquehanna International Group (Melbourne) in Jan 2022
Interview
This was the first stage of interviews consisting of a short math exam, timed for 60 minutes. It was comprised of questions on probability, calculus and combinatorics. The exam was divided into four sections: all questions in the first two sections must be answered; sections three and four were optional and contained slightly more challenging questions. I did not proceed to the next stage.
Interview questions [2]
Question 1
All the questions could be completed using pen and paper. For one question, typifying calculus questions, you were given a complicated function and were required to evaluate its fifth derivative at zero.
In one question, typifying probability questions, you were asked to evaluate the probability that a linear combination of two uniformly distributed variables would be greater than some given value.
OA is same for New Grad / Intern Traders / Researchers I believe. 17 questions in 60 minutes; after OA some phone interviews and final on-site. OA was doable if you practice right prob. / logic questions etc.

Question 1
Five toddlers are to be seated next to each other. However, Alfie does not want to sit next to Bert/Erving. Bert does not want to set next to Charlie. And Diego does not want to sit next to Erving/Charlie. Who sets next to ...?
I applied online. I interviewed at Susquehanna International Group (Dublin, Dublin) in Nov 2024
Interview
5 stages (after passing a CV screen).
(1) One-hour online maths/probability assessment;
(2) Phone screen with HR: behavioral and easy probability (easier than the online assessment IMHO) questions;
(3) Video interview with trader, slightly harder probability questions that are set in a betting/market-making context, followed by some CV questions about technical skills (coding, internship projects);
(4) Data analysis / modeling take-home; this seems to be specific to the "systematic" trader role I applied to.
(5) Final round.
Tips: practice explaining your calculations out loud. The stage (2, 3) questions are not hard, but can put you off if you are not used to explaining where your numbers come from.
Timeline: slow process -- took 2.5 months to get to stage (4). Waited ~1 month after stage (1), and ~2 weeks between subsequent stages because interviews are hard to schedule.
I interviewed at Susquehanna International Group (Sydney)
Interview
Basic HR questions followed by 2 probability questions and general CV questions about exper ience etc . Seemed to me that i did good but did not get to the next round
