I applied online. The process took 2 weeks. I interviewed at Susquehanna International Group (Dublin, Dublin) in Mar 2022
Interview
-1 hour online coding test, basic leet code style questions algorithms and data structures etc.
-1 hour online call with recruiter about my past experience, recruiter was very friendly
-1 hour technical interview with two engineers. In depth questions about data structures, time complexity, object oriented programming, and concurrent systems
Positive technical interview experience, when I didn't know the answer to a question, the interviewers would give hints or explain the answer to me so, so it was a good learning experience.

I interviewed at Susquehanna International Group (Philadelphia, PA) in Jun 2026
Interview
- initial phone screen
- technical round (follow up with recruiter next day)
- technical + design round (pre and post interview calls with recruiter)
- in-person fit/experience talks (pre and post interview calls with recruiter)
I realize this sounds like a ton of meetings (and it is), but I appreciated the straightforwardness of the process and the amount of feedback I got, which I think is rare among interviews.
