Pros
Excellent work/life balance: flexible work environments, generous PTO, collaborative team environment, and the 'day ends at 5 o'clock' mentality. Compared to other corporate environments, Hilton's is the best I've experienced.
Cons
The company is huge so it is hard to effect change across multiple teams or departments. It is easy to be pigeon-holed and get good at one 'thing' and then be stuck doing that 'thing'.
