Avantages
For a finance professional living in an Engineer's world, the pay was great as were the benefits. Job opportunities are abundant, varied and career progression is real. The company has done a nice job (recently) of adopting newer technologies that are more becoming of a world-class industry powerhouse. The campus in Spring, TX also helps.
Inconvénients
At ExxonMobil, pretty much everyone thinks they're going to be the next CEO, but I guess that's to be expected at place where they recruit with that in mind. This gives way to a terribly homogeneous workforce (even if there is diversity of race and gender - see Advice to Management). In a culture where everyone wants to lead, collaboration suffers, innovation lacks and progress is inhibited. The rating & ranking process is shrouded so it's hard to get a good understanding of what's really valued and what is not. Some managers are fairly open about the process, while most are tight lipped. No surprise, then, that this leads to misinformation, speculation and confusion.
