Pros
Great opportunity for career advancement. Great people to work with and overall a good company. Being an intern I didn't receive any true benefits from the company. The compensation was very fair and there is a great balance of work and life within the organization. Everyone working there seems to be very driven and technology oriented. Chicago Mercantile Exchange Group has a very large IT department and is very fast paced. The company is ranked by Computerworld's magazine as one of the best companies to work in IT. CME Group also has great growth potential and is one that can offer a good variety of job opportunities.
Cons
Organizational structure is questionable and manager performance can be sub par at times. Workload can be somewhat demanding at times and will often require additional hours to be put it on the weekend for the busier weeks. With a large IT department within the company there are times when communication is not effectively established across given departments which in turn hinders the work process. The overall structure of the company is efficient, but at times it seems as if the two divisions are organizations of their own which can cause some slight problems. Other than that, in my time there I didn't experience too many major downsides to CME Group.
