Pros

Great Projects, people are really smart, and you get extensive knowledge of the financial industry.

Cons

CME does an awful job of handling their consultants. They treat them very poorly going out the door. I saw two instances where giving CME 2 weeks notice worked against those people. In one instance the consultant gave notice at 9 AM and was kicked out before 10 AM. The second instance a consultant gave notice EOD Monday and was let go EOD Tuesday. More than a few supervisors have less than stellar communication skills (i.e. snarky, rude, snide, condescending commentary is the norm).

Pros

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.

Cons

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.
