I applied through college or university. The process took 3 months. I interviewed at Susquehanna International Group (Bala Cynwyd, PA) in Jan 2016
Interview
First round was a 30 minute HR screen. Second round consisted of an online coding challenge, followed by a phone interview with an engineer about your solution as well as your resume -- also covered database design and data structures. Didn't hear anything for two months, which was followed up by an on-site interview. The on-site was 3 rounds. First an on-site coding challenge (with computer) followed by two hour-long interviews with groups of 2 engineers each (writing code and concepts on whiteboard). The interviewers were all very helpful and supportive. Then finally a tour of SIG facilities to wrap up the day.

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.
