Pros

It’s pretty awesome to be a part of a startup that has the backing of a huge company. Things move quickly at Symbioscience, which allows new employees (called associates here) to have an impact from the start. There’s been a lot of growth recently, both in terms of the company and the leadership. The leaders saw a need for increased focus on employee engagement, and have devoted a lot of time and resources to it over the past year or so. You can also see that they took to heart the need to be more clear and transparent about the segment’s strategy, vision, and direction with associates. Being here, you can see the effect of what they’ve done (or really even just sense the improvement in the atmosphere). The segment just got back their Gallup engagement scores, which not only improved a ton, but were also some of the highest in all of Mars.

Cons

Change is constant at Symbioscience, so if you’re not comfortable adapting, then you’re not going to like it here. Being a startup, it’s a small group, so you also have to be okay with getting your hands dirty and pitching in beyond your official role.

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.
