Pros
PAREXEL has been very fair in my career development and helping me to achieve my career goals. My direct manager is very fair and work life balance oriented. I feel part of the reason I have been successful is my take initiative attitude. I have seen others fail who might very well be a great employee but they get left behind in the "sink or swim" environment.
Cons
Upper management is so disconnected from the actual work that their decisions and policies are not always effective or wise. Some of the tools provided are too complex with little or no training. It is expected that you will "figure it out on your own" but at the same time are reprimanded for figuring it out wrong. Upper management seems to have a "do as I say attitude" with complete disregard for employee comments/suggestions. It can be very frustrating.
