Pros
Dow is a large company, and offers the opportunity of moving between roles and gaining a breadth of experience. They are major part of a keystone industry.
Cons
It is a very large corporation, and it is hard not to feel like a cog in a giant machine. Management and coaching is not encouraged or rewarded, so little opportunity for mentorship and guidance beyond your own wherewithal. Dow is a bit of an old boy's club, and promotions are influenced by who you know and have worked for and how much political capital they have with leadership. The industry is old fashioned and lacks an innovative and face paced environment, and this is true through much of the company. Dow wants to be an innovative technology leader, but is caught in its hedge between old school commodities for which cost cutting and efficiency are the keys, which are its bread and butter, and advanced technologies further up the value chain. Dow isn't risk tolerant to place the financial bets and invest in a different type of human resource to really transform as a company.
