I applied online. The process took 2 weeks. I interviewed at Susquehanna International Group in Jan 2021
Interview
Initially had to do a 20 minute test on statistics which had 15 questions. Then had a 45 minute phone interview with a HR person and then another interview with a quantitative trader.
Interview questions [1]
Question 1
Probability questions and general background questions
I interviewed at Susquehanna International Group (Bala Cynwyd, PA)
Interview
One hour online test consisting of topics including probability, combinatorics, and logic. The test consisted of 17 questions so look to complete one question in around 3-4 minutes and leave yourself some time to check for mistakes in the end.

Question 1
If knights only tell truths, and knaves only tell lies, A & B could be either or both knights and knaves. A says: we are both the same type. B says: we are different types. State the type of esch of A and B.
Interview was very nice and easy to talk to, they obviously wanted strong mental math/ probability skills but also a competitive mindset
