Former Intern - FLP Intern

I worked at Aon for less than a year

Pros

Awesome culture and the people are all so happy to help

Cons

Wish I learned more

Former Employee - Senior Client Advisor

I worked at Marsh & McLennan Companies full-time for more than 3 years

Pros

The Marsh brand is a big name in insurance and carries a lot of weight with clients, carriers, and others in the industry. There are lots of resources available to you if you know where to find them.... You will have access to many talented and experienced colleagues.

Cons

Change comes slowly in a large organization like this. There is little thought given to the size or makeup of the book assigned to you. Work/life balance issues. Management ranges from excellent to... incompetent (and everything in between).

Advice to Management

Your greatest assets are the Marsh name and your employees.
