Pros
Be a part of a best in class organization. There are always new challenges and if you have an open mind and want to take part in exciting endeavours, this is the place for you. There is an outlook that if you give then you will get, so if you continue to contribute and add value, you will be rewarded with opportunity. Training takes a few different forms with mostly on the job, but then there are many training programs that really you just need to ask for, there is also tuition reimbursement. Compensation is competitive and it really can be a job for life. Opportunities often come in the form of international assignments, so don't be quick to disregard them they will usually lead to career growth; the company is very understanding and flexible and will usually work with personal situations but don't be a primadonna.
Cons
Not a place for the faint of heart, there are continual challenges and your bandwidth will be tested. Clock watching will limit your career aspirations here, it is a lean organization and those who don't pull their weight will be quickly identified and miss out on opportunity.
