I applied online. The process took 1 week. I interviewed at CME Group
Interview
initial HR screen then a tech phone screen over coderpad. didnt make it past this, but i heard it was the onsite. I had completely forgotten the interviewer said you can google and since i was getting flustered with using java cause i havent used java before, i completely forgot to use google. there were a lot of syntax errors i was having which got me frustrated. Other than that, I honestly did pretty well in the interview as we had talked about complexity, how to improve it, what data structures to use, all that jazz. and he agreed with me on my choices and my thinking. I come to find out when asking for feedback, that he said although he's definitely competent, I was disappointed by his debugging skills. I COMPLETELY FORGOT TO GOOGLE DURING FIXING THE SYNTAX ERRORS AND THE INTERVIEWER HELPED ME OUT. I DONT UNDERSTAND WHY DESPITE HAVING A GOOD SENSE OF DATA STRUCTURES/ALGORITHMS he'd tell the company to pass on me. honestly so freaking dumb...
Interview questions [1]
Question 1
basic string/array question regarding counting all unique strings (unique being if the string and the string's reverse exists)
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.
