I applied online. I interviewed at Susquehanna International Group in Oct 2021
Interview
Technical phone review with recruiter at the firm. Two questions about probability that are moderately difficult. The interviewer was nice and provided hints when I gave wrong initial answers.
However, I think you can only pass the interview if you answer the question correctly at first try.
Interview questions [1]
Question 1
Medium-difficulty probability question (conditional probability etc)
I applied online. I interviewed at Susquehanna International Group
Interview
Difficult brain teasers. Lots of math and probability, need to think fast in order to answer all the questions in time and prepare a lot. Very limited time and very difficult questions you have to answer quickly
I interviewed at Susquehanna International Group (Philadelphia, PA)
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
