Pros
Structure, Structure, Structure! If you are a person that enjoys structure in your life, then Dow is the company for you. There is a work process for every group (Engineering, Operations, Maintenance, etc.), a procedure for every task, job descriptions and boundaries for every role. This is not necessarily a negative as the chemical industry needs this type of control due to the hazards involved with chemical processes.
Kontras
Like many large companies, politics rules at Dow especially around promotions. You can work hard, get very good performance reviews, good bonuses and positive feedback from peers but if you aren't in the "click", you aren't going to get promoted. If this happens, you need to move on to another site or function within Dow or pursue employment outside of Dow. Don't waste your time trying to "wait things out" because once the promotion block is in place, it won't be easy to remove.
