Pros
Work with lots of smart people. High impact due to scale of company. Good place to start career and then move on. Dow will use you, but you can use them too.
Cons
Well-known for its arrogance and bluffing. Senior leadership has made costly errors and employees are paying the price. Forced rankings, targeted terminations of older employers under guise of forced distribution (do the math: cut bottom 10-20% each year and how many years does it take for older employers to get the hatchet, especially if they are targeted by management using subjective assessment criteria?). Focus on cost cutting instead of spending appropriately to buy success. High turnover in management and leaders. Frequent reorganizations. Lack of stick-to-itiveness as goals and strategies constantly change. Excessive politics. Reneged on work-life balance promises. 24x7 work schedule with email and cellphone tether to globally distributed sites.
