Susquehanna International Group Software Developer Co-Op interview questions

I applied through my university, at the very last minute. Got phone screen within a week, and onsite after another week. I interviewed with multiple teams, and was asked architectural questions, as well as some small coding problems. I was able to answer most of them correctly, thanks to some of my contributions to open-source. Got an offer within two weeks of interviewing.

Was contacted for a phone interview asking basic questions. Once selected for an in-person interview, had 3 individual interviews over a 3 hour period. This included 2 interviews with people from different teams at the company. Each interview quickly went over my resume and contained numerous technical questions. The final interview was with a hiring manager going over the job details.
