Pros
Diverse product portfolios and business groups lead to a breadth of business opportunities that could allow someone to spend their entire career with one company while presenting them with experiences in a variety of markets (Consumer, Safety, Industrial, Electronics, etc.). Core Benefits are solid (Medical, Dental, Vision, etc.), but don't expect any cool perks you might find at SaaS or Consulting companies (Sports tickets, unlimited PTO, free branded merchandise/swag, networking events, Presidents club, consistent sales incentive trips).
Kontras
3M has a growth problem due to its internal complexities leading to often times a poor customer experience, an indirect model that makes it difficult to measure end-user sales impact and lack of product innovation which results in pushing antiquated technology/product platforms in the market at a premium price in comparison with competition. In addition to the growth problems, multiple lawsuits loom over the company. From a sales standpoint, the variable compensation system in the U.S. is too complex. Managers and Reps are often times unable to explain it, which is a problem. Additionally, sales organizations are antiquated about their go to market strategies and how to best deploy coverage models within target markets compared to modern sales organizations traditionally found in the SaaS space with clearly delineated roles and responsibilities (BDR/SDR, AE, Sales Engineer, Customer Success, etc.).
