Still has opportunities, but culture has declined - Anonymous employee CME Group Employee Review

good pay, interesting work, good people

very very little work life balance

Strong engineering culture with exposure to large-scale financial systems, distributed architecture, and production-critical platforms. Good opportunities to learn modern cloud, performance, and reliability engineering.

Bureaucracy and internal politics can sometimes outweigh technical merit. Employees who take ownership or challenge inefficiencies may face delayed recognition, unclear growth paths, and shifting expectations, leading to frustration and disengagement over time.
