I applied online. The process took 1 week. I interviewed at Susquehanna International Group in Sept 2022
Interview
A day after applying, I received an email asking me to take the SIG Problem Solving Assessment within seven days. Instructions and topics covered were provided. The assessment was quite difficult. If you are not using statistical equations and calculus in your work every day, probably you are not going to remember some of the techniques they were testing, even if you've taken classes in these subjects before. After I completed the assessment, a few days later I got an email that they would be moving forward with other candidates.
Interview questions [1]
Question 1
"Basic" probability, statistics, and calculus questions. The questions could all have been solved with a brute-force method, but there was a time limit, so it was clear you were supposed to know some clever way of figuring out the answer quickly. The quick method was obvious for some questions and really not for others, and again would be much more obvious if intro stats and calculus were topics you used daily even years after completing the courses.

Interview
The first hurdle in SIG’s interview process is an online assessment administered through Mercer | Mettl. It tests knowledge in mathematics, probability, and statistics. The assessment combines puzzles and probability questions, along with topics like expected value, combinatorics, and logic. Overall, it follows the standard quant interview format — probability and statistics are the most critical areas to master before sitting the test.
An online math test testing topics such as probability theory, basic logics and word problems that you need to do in a relatively short time. I was not invited for further interviews
General question such as background and motivation then 2-3 math questions based on probability and expected value. Difficult than OA. But overall, it is managable if you have done a proper review.
