SIG Technology Internship Second Round Interview

Hello,

I'm a Junior in college major in Electrical Engineering and Computer Science. I am having a second round interview with SIG for the Technology Summer Intern: Software Development & Systems Engineering. They asked me about the probability problems during the first round interview and informed me the second round interview will be more technical. I searched around on the Internet and most of the interview questions that I could find are for the Trading internship positions. Does anyone have any examples of specific questions? Should I be expecting algorithm questions or more probability questions?

Thank you.
