Pros
Decagon is a company that has experienced solid growth for the past 15 years, and are poised to continue that growth. Their staff of in-house R&D scientists provide good solid direction on new product development. The development teams are cohesive and use effective collaborative tools to get things done. As others have mentioned, there's not a lot of micro-management, which can be liberating for some, but perhaps discouraging for those who like more oversight. Employees are held accountable for getting work done, however. Decagon also has some of the best benefits in the region, and the Pullman-Moscow area is a great town to live and raise a family.
Cons
It's important to remember that this is a family-owned company for the most part. The Campbell's started this company and they therefore have a vested interest in keeping the family interested in the company's future as much as possible. Some can be put off by this.
