Pros

High expectations on performance are matched by levels of freedom. It is a principally (see below) meritocratic and relatively concensual culture: once you have invested up front in getting everyone on-board things can happen fast. In general you have a big say in your future development in the business and there are plenty of opportunities to move around the world with the business, if that is what you want.

Cons

The Mars leadership norm is extroverted and verbal, matching the businesses US origins. If you do not match this style, no amount of performance or personal development will get you into the upper echelons. The culture loves change and dynamism and consequently passively resists structure & systems, so lean processes are difficult to embed for example. The business is respectful of the individual but this must not be confused with caring !

Pros

Nice people and a known brand globally

Cons

There's absolutely no career growth - 0 structure, you have to play politics and not upset anyone (which means it's better to do nothing than drive value & impact). Seen completely incompetent people become VP/CDIO (switching from MW to Pet Nutrition) with 0 understanding of value or analytics and just doing "RACI" type discussions (current CDIO of Europe in PN). P&O (HR) is COMPLETELY USELESS - they have no idea what's best practice at other companies, it's mostly young and incompetent lifers, having worked nowhere else. There's absolutely no support beyond talk for career development in analytics. New CDO does nothing but politics in MW (constantly going to "workshops" for 2 years). No one at VP level knows analytics, they just play politics. Looking to do the dumbest acquisition in CPG since the Heinz/Kraft merger. K's stock price has been tanking for decades, but here we are - acquiring a company that's high in sugar & salt rather than healthy (where all of the growth is). MW CEO wants to become the Mars Inc CEO, no doubt, and apparently this is needed for that? Horrible horrible acquisition.
