CME Group Software Engineer Interview Questions
& Process

i cold applied online and then did an auto OA with two LC easy questions, which was pretty chill. then i had an hr call, which was a bit unusual cuz i got moved into a more competitive yearlong program pipeline. after that, it was the first round which was a 1hr tech interview with a standard LC question. the final round had a 15 min behavioral interview and a 1hr system design. then i got the offer! for the interviews, both OA and the final round used Glider, which was a pain due to technical issues. round 1 was a LC easy array question (took 5 min) and they asked if i preferred Java or Python. round 2 was a 15 min behavioral with HR, pretty standard stuff like 'why CME?', 'why this position?', and 'what would you do in X scenario?'. the 1hr sys design was about designing Uber but with a really specific, non-standard requirement: a deep dive into APIs, detailing every field, its type (like VARCHAR(<255)), primary key for every single SQL table. they also wanted a UI sketch on Glider. my interviewer was super nice and helpful with the Glider issues and gave hints. there was also a scheduled HR feedback call on my resume where they mentioned CME reviews all resumes by humans, not ATS, and to put skills after education, show depth in one area, and include non-academic extracurriculars to be memorable. also, it's a must to include project dates even though Glider is bad. everyone i interacted with was great, and HR was good with rescheduling.

You'd probably start by giving a quick rundown of your work history, what you're good at, and what you've done, touching on your education, projects, or internships that fit the role. Then, expect some technical questions, especially on Object-Oriented Programming (OOPs). They'll likely ask about core OOP concepts like classes, objects, inheritance, polymorphism, encapsulation, and abstraction, and also how you'd implement things like object creation, method overloading/overriding, and using interfaces or abstract classes.

The interview process involved four technical rounds. Overall, it wasn't too challenging. However, CME's communication could be better. After completing four interviews, they took 5 weeks to inform me that the position I applied for was filled. Additionally, their other office did not respond to my emails regarding scheduling an interview for a different role.
