Pros
The compensation is fair, however depending on which department you work in, your experience will be vastly different.
Cons
Highly segmented company, different departments in many different cities and no plan to consolidate anytime in the future. Very difficult to get consensus across departments due to the "silo" approach. Best analogy came from a co-worker, they run the place like a mom and pop liquor store. People are friendly, but only superficially. Everyone seems afraid to speak out against bad processes. If you have the fortitude for it, and don't mind the 1960's mentality and decor, then Mercury is for you! Not at all progressive, like swimming in concrete. Lots of "secretaries" keep the manual processes running. Their bosses don't seem to be very current on best practices and leave it to chance.
