Pros
Pay seems to be the best for Chemical Industry. Seems to have a high level of investment performance when compared to most competitors. If you are ranked highly you will be well taken care of.
Cons
Seems to be the red headed step child of ExxonMobil. Upstream is clealry where the money is mostly made and where everyone wants to be. Seeems difficult to make a move from Chemicals to Upstream. Refining even seems more respected than Chemicals. Ranking system is very subjective and tends to not be based on anything quantifiable. Career Development is handled totally by management and not by the individual. There are no posting of jobs for professionals. All job moves are handled internally through your supervisor so relationship with him/her is very important.
