Pros
You are guaranteed to meet great people with great ideas and be exposed to some fantastic technical challenges. The salary package, though certainly not world beating, is satisfactory and the final pension scheme remains one of the best. BP has a rather informal feel, which makes the office environments pleasant and relaxed places to be.
Cons
BP are a big company which still acts like a small one. Frequent shifts in "strategy" to satisfy the analyst's short term demands have inevitable long term consequences and we continue to feel the pain of past mistakes on investment, access and staffing. Let all the BS 'wash over you' and you'll be fine .... expect to be buoyed by insightful and innovative corporate decision making or expect to see your share options go through the roof and you'll be disappointed. The big question is; will we survive in our current form?
