I applied online. The process took 1+ week. I interviewed at CME Group (Chicago, IL) in May 2015
Interview
I applied through online. I got the mail from the recruiter the next day asking for phone screening.
Then After initial screen, recruiter mailed me asking for technical phone interview. I had taken the interview two days after that. The lead and another software engineer from the team called me for the interview. It was around 30 minutes. They generally asked about core java, SQL, queries. And, Linux which I said I do not have much experience. They asked me any questions from my side. From which, they asked me counter questions regarding the company. Then, I got the offer a week later.
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.
