      Pros

      Excellent training options for employees, many perks and benefits

      Cons

      Poor management at multiple levels; some were competent and quite good, others were incompetent running programs for which they were ill suited and non transparent, even secretive. Patronage system.

      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.
