Susquehanna International Group Software Engineer - Intern interview questions

Quick phone interview which involved some technical questions and explaining why I'd be a good fit for this position. This was followed by whiteboard coding interview via zoom, which involved answering 2 questions which had multiple parts, as well as some theory questions.

First round interview on campus, mostly behavioral questions, few basic object oriented questions (polymorphism, encapsulation, etc.) and then a probability question. Second round phone interview, some basic object oriented questions again and then network programming questions.
