Pros
Mars promotes a open, collaborative environment where top level management to the entry level associated are treated as equals. There are plenty of opportunities to move to different (lateral) positions during your career. The benefits are good for a company of this size, but not the best. Finally some of the of the most interesting and nicest people you'll meet are those who've been with the company 30+ years.
Cons
Mars seems to only recognize associates who are extroverts. Introverts, results \ performance based associates are typically overlooked for advancement if they lack the "schmoozing" trait. This results in many people whom you might work with being completely superficial about building friendships \ relationships. If it is discovered that you may or may not have any influence over someone's advancement, the relationship building seems to die off quickly with the more ...ambitious associates. Diversity is woefully sad \ absent. While there are some examples of women and minorities being promoted, minorities are pitifully underrepresented in middle \ upper management (if existent at all). Diversity of thinking \ thought is promoted, yet Mars management heavy culture produces managers who are all white males, uniformly dressed in the same color shirts, and are slow to think outside of the box. It literally is a group-think culture. Mars is middle management heavy. Which makes navigation much more complex than it should be. Which means that an idea, project plan or a proposal must be run through a gauntlet of managers first if to be given the green light. If one manager is absent or disapproves of your approach, plan for a delay. Until there is a consensus, your project is going nowhere.
