I applied online. I interviewed at Susquehanna International Group
Interview
Online math assessment. Make sure to follow the instructions and do not skip around on the questions, a you cannot go back until you have answered everything. Some basic calc and probability questions, some combinatorics and recurrence stuff that was not too bad, but time pressure and not following directions hurt me.
Interview questions [1]
Question 1
What is the last digit of an expression w/ exponents. Olympiad style stuff.
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
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.
