I applied through college or university. The process took 4 weeks. I interviewed at CME Group (Chicago, IL) in Oct 2016
Interview
The overall process was fine but for the onsite interview I arrived at the hotel and was asked to pay for the hotel through my own credit card because the recruiter was having issues booking a proper hotel. I have been waiting for my reimbursement for almost 5 months now. The HR department has showed a great deal of unprofessionalism in this regard.
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.
