I applied online. The process took 2 days. I interviewed at CME Group (Chicago, IL) in Jul 2014
Interview
Applied online and heard back about a week and a half later. Via email set up a time to speak with HR representative. We then set a time to speak with software engineers who were part of team I'd be working with. This was a phone interview which lasted about 25 minutes. They ask about past projects and then went right into Java questions. Difference between inheritance, abstract, and regular classes. Difference between a list and a set. They then asked a couple of questions relating to test driven development.
One call with recruiter who asked very basic questions but told me about hte position. Hour zoom with hiring manager with many technical questions. It was tough to understand with his hard accent. Another in-person meeting with two managers.
phone call oa and then a take home and finally a superday with sys design as well as some medium leetcode problems. overall i would say pretty standard for software engineers. also behavioral call with hr
I applied through an employee referral. I interviewed at CME Group (Belfast, Northern Ireland) in Nov 2025
Interview
There was one assessment day that consisted of a group interview and a individual technical & software skills interview.
Everyone was really friendly and helpful throughout the entire process, with the interviewers doing a great job guiding you so you show the full extent of your knowledge on topics.
