Pros

5 Principles: You have to be a Mars person (or Martian!) to know them, but they are applicable to everyday life and guide all interactions Mars has internally and externally. It's nice to have a framework within which to make decisions. They are fond of hiring ex-military, have good FMLA and other benefits. Once you're Mars, you're always Mars.

Cons

A bit of an old boys' network. Very traditional in places, as it is a family-owned company and those tend to be places where women struggle to advance. Not very good work/life balance. Once you're Mars, you're always Mars.

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.
