Pros
Dow has a relatively good culture of people which is one of the best parts of working there. It is almost guaranteed that you will work on very challenging and meaningful projects/endeavors during your time. They have a 9/80 schedule for most employees except for shift operations which is nice. They also have good 401K matching and an employee stock purchasing program if you choose to participate. Dow is also relatively good at letting you choose your career path compared to some other big oil/gas/chemical companies out there. You are usually not stuck in the pipeline of the job you're currently in if you don't want to be and work hard.
Cons
Dow pays a good bit less than some of the competitors, yet works you harder. I have friends at all competitive companies and they all make more than me with the same or less years of experience. They also have less responsibilities in similar comparison roles to mine. I find that I am working many more hours and have a lot more responsibility than my peers at other companies yet I am not compensated for it. This is a challenge as I find i don't get to utilize my 9/80 schedule like I would like to as I'm often working. Production engineering is very busy and truly is a firefighting job. If you like that, then you may like a production engineer role. Fight for a higher salary if you can, because dow will work every hour out of you. There is no overtime for salary, except in certain situations where they give you a very small percent of your salary for no matter how many hours you work over 65 in a week. Its disheartening as Dow gets my time and efforts for free a lot of the time.
