I interviewed at Susquehanna International Group (Sydney)
Interview
First an online aptitude test with your basic probability and mental maths problems, then a phone interview with 3 more maths type questions followed one by a teams interview. Did not get past this point
Interview questions [1]
Question 1
You are playing a game where you and your opponent have put $10 in the pot each. Your opponent bets another $10. What is the minimum probability of you winning to call this $10 bet?
Lots of easy rounds, easy final round unclear how they differentiate between candidates. People are very pleasant, amazing office (philly), but interview process is weird, they should ask harder questions.
I applied online. The process took 3 months. I interviewed at Susquehanna International Group (Dublin, Dublin)
Interview
Fairly enjoyable, a few math questions but mostly general market awareness and behavioural. 3 rounds, first is with HR, then with analyst and the final round is with the head of the team.

I had to complete an online assessment for SIG as part of the application process. It included logic, probability, and mental math questions to evaluate my analytical and problem-solving skills.
