Pros
Hilton is one of the most recognized companies in the world. A job there brings instant credibility and instant respect from your professional network and prospective employers. The culture is generally supportive. Colleagues work together in a constructive and collaborative way. There are many opportunities to work on international projects and learn how to conduct business on a global scale. I learned a lot while I was working there.
Cons
The company is not very family-friendly. The people who get the most out of it are either very young--i.e. no children--have no children, or have older children--college age or older. The work can be exciting but there is a LOT of it. They run a lean operation over there and they're slow to add headcount as the workload increases. This means logging lots of time at the office to get things done. Also,while their global reach is a huge plus in many areas, it also means a lot of business travel to keep things going. If you have small children and a spouse that works, it can get pretty crazy at home. Meanwhile, their compensation, while nothing to sneeze at, doesn't go very far once you have to shell out for childcare every day. Senior management likes to talk about how work-life balance and employee satisfaction is important to them, but I didn't see them taking many concrete actions to improve it.
