Pros

Many learning opportunities. Flexibility within the organization for decision-making and ideas. An open-minded mentality gives you a voice, regardless of your position. Networking opportunities are not uncommon; many plant visits, employee resource groups, and company events facilitate this. Friendliness is a driving force in an otherwise productive environment; everyone is always willing to lend a hand and share their knowledge. Recognition; You will be recognized for your work, no matter how minute the task. Overall, this will put your foot into a door where you'll be welcomed and encouraged to grow, with support from all sides.

Cons

Need more flavors in the water dispensers!
