Pros
Working in the Oil&Gas industry in today's climate (no pun intended) is pretty secure. This a secure industry/sector and you don't have to worry about redundancy. Your overall work life balance really depends on your manager and supervisor. If you're lucky you're going to have a really nice, caring and emphatic supervisor that could make things easier for you, but if you're unlucky your life will be a living hell. Once a week they bring fresh fruit to the office and during summer they hand out ice cream. Most of the people in the office are nice and cool people to hang out with and we have a great team spirit. Everybody could find their "tribe" or your office bestie.
Cons
The downsides of working for ExxonMobil really varies depending on your location. Most Europeans would find the work culture "too" American which is a nice way of saying toxic. They are one of those companies who forced us to come back to the office and took away our home office days. I guess they love micromanaging. They are also one of those companies who make billions of dollars ( in pure profit, after tax) which they love to rub in your face at every town hall however they barely give you a pay raise. All those cash goes to their shareholders ( which they love to brag about) rather than paying their employees. They have created such complex safeguards to gate-keep you from moving forward in your career that it's almost impossible to earn a decent salary. Even if you get a promotion and you secure a higher position within the company you're not getting a higher salary automatically. You will have the experience like many of us, that you will train a new joiner who just joined the company from outside and already making twice as much as you do who already worked there for years. They don't value your work or expertise, in true American fashion they will try to squeeze the most out of you before you burn out and you choose to leave the company. They don't care about inflation and cost of living crisis ( in Hungary it's record high) they are still choosing to under pay us, especially compared to our colleagues in the USA, who make a lot more ( like a LOT MORE) than us, doing the same jobs. The American colleagues are also very smug and they look down on us which makes the day to day work pretty difficult. The company expects you to understand and execute very American specific tasks but they don't fund trips to the USA to learn from your fellow colleagues nor they fund a more comprehensive trainings. They don't splurge on company events either and even if they do, the event is really strict and they barely give you anything to drink, besides a few glasses of the cheapest wine and the worst beer imaginable.
