Real, anonymous reports from people who interviewed for Software Engineer at CME Group, newest first and distilled into what to expect across the loop.
I got connected through a career fair and the whole thing moved fast. It was basically just a quick recruiter-style chat with very straightforward behavioral questions—nothing heavy, just the usual “tell me about yourself / teamwork / why this” kind of prompts. The interviewers felt like they were on the friendly side too, like they’d recently been interns themselves, and that made the tone feel almost informal.
After the initial outreach, my process turned into a pretty smooth technical run. I ended up with a sequence that started with coding—either an OA-style assessment or a coding round done on a platform—then moved into live technical work where the interviewer guided me while I walked through the solution. The tone felt warm and collaborative, like the interviewer wanted me to succeed and kept me moving when I got stuck.
