Pros

Privately owned company where the family is still heavily involved, either directly or through their continued advocacy for the use of the Five Principles as a decision guide post. Great, talented associates who are allowed to thrive in a great culture.

Cons

You either love or hate Mars. If you're an independent self-motivated individual that continually upgrades your skills through self-learning and self-improvement, you'll love Mars. If you want to just float along, you'll quickly fall behind your peers and not enjoy your career experience.

Pros

I’ve been at Mars (Yorkville site) for about three months as a Quality Systems Senior Specialist, and so far it’s been a great experience. Everyone has been genuinely friendly, welcoming, and willing to help. The culture feels very supportive—people want to see you succeed and are quick to share knowledge and offer guidance. My manager has been amazing and is truly invested in my growth. She’s helped set clear expectations, encouraged development, and provided the tools and support I need to be successful.

Cons

None so far—still new, but my experience has been very positive.

Pros

Great people who believe in a common mission. Strong leadership and support.

Cons

Budgets and decision making for technical programs are centralized at a high level with little to no consideration for how it affects individual programs and their unique needs. Heavy bureaucracy involved in setting up simple things.
