Pros
First off please note then when reading other's reviews that there are MANY divisions and companies under the ThyssenKrupp name. Do not allow other's negative reviews deter you from the company as their experience is of their division only. I personally work for the Industrial Services Division under ThyssenKrupp Materials NA which I can't recommend enough. There is a tremendous amount of growth opportunities available. You get out what you put in. If you have a passion for what you do it will show. If you provide solutions and are actively engaged you will be rewarded. They have an excellent benefits package and 401k plus profit share.
Cons
The culture is under repair and being put as a top priority via employee culture surveys. There is nothing wrong with the current culture but as with any organization there is always room for improvement.
