I applied online. The process took 3 weeks. I interviewed at Susquehanna International Group
Interview
Phone screen followed by 5 hour interview. In person consisted of practical language agnostic coding challenge followed up with optimization questions, then current work description(how would you improve your current jobs software) and data modeling discussion(how would you model a system to suit these needs), and finally questions about my past accomplishments. All interviews were done in teams of 2, all by long term knowledgeable engineers.

Question 1
movie sorting problem, different genres search by year
I applied online. I interviewed at Susquehanna International Group
Interview
The OA consists of four LeetCode questions, needed to be done within 70 min. Highly recommend revising how to do the int-string conversion in the language you will use. The problems themselves are not hard, but better to have a clear high-level view before you code.
