Pros
Global company with opportunities for people with specialized technical skills.
Cons
Don't expect loyalty beyond your immediate manager. I was transferred from Minneapolis to Australia with my family and then was laid off. The company wouldn't bring me or any of the others back to a job in the United States. Our former managers were sympathetic but did not help find us new positions. We were on our own. It isn't easy to have you 5 year old starting kindergarten in Brisbane and explaining to him we are pulling him out of school and don't know what country we are going to next. I ended up going to work with a competitor and have done very well since then. Don't expect anything from this company beyond what they are required by law to do, such as a paycheck. Being fair, this seems to be the mindset amongst the engineering consulting business in general nowadays.
