I applied online. I interviewed at Susquehanna International Group (New York, NY) in June 2022
Interview
First there was a screening test online that was fairly easy. All math problems: basic precalculus with an emphasis on probability. Then there were multiple rounds of phone interviews focusing on probability questions. These were harder, though still using only elementary tools and techniques. Then there was a pre-final stage involving questions on research and
Interview questions [1]
Question 1
Suppose there are 16 tennis players in a tournament which proceeds by single elimination, with randomized pairings at each step. What is the probability that two given players play each other at any point in the tournament?

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.
