Pros
If you work hard, know your stuff, and can navigate corporate politics you will grow. You will get more responsibilities, higher titles, and more money. Some of the most talented, hard-working, and knowledgeable resources I have ever met. I felt bad for a lot of them, because I think that if they knew how to navigate politics better, or how to sell themselves better, they'd realize how much better it is outside XPO. The opportunity to learn in a trial by fire. You will work with millions or billions of dollars, you will be expected to make things better, and if you don't they will not have a problem with parting ways with you. Your resume will look great if you learn by doing, because you will have plenty of opportunity to do.
Cons
The higher you get paid the more politics, inefficiencies, and chaos you will have to deal with. The bad and funny part is that there is no plan to make it better, and all you do is wait for something to break, and only then does upper management even think about it. You have no voice. Management spent more time trying to figure out how to improve the internal survey ratings with food than actually listening to the feedback from the employees. No work life balance, you support global teams and high-expectation customers. You will be online all the time, you will be on call, and you will work late. There are a lot of tenured "professionals" that are lifers. They have found a way to coast, and they are Minimum Viable Performers. They understand the system, they get 4-6 weeks of PTO, and they know that there is process before they can get laid off. Usually taking 6 months and some level of notification like a Performance Improvement Plan which they can adjust to. To enact change is like to rewrite the constitution. There is an endless amount of unknown processes, approvals, and escalations you will have to navigate before you start enacting change. Escalations are the only way to get things done, usually it is you escalating to someone else's boss, and then you escalating your boss to talk to that person's boss. Relationships are everything once you get to this level.
