Pros
Expedia is filled with very smart people from whom you can learn. There is plenty of growth opportunity if you are willing to define your own career path and go after it. While a large organization, there is still a focus on how to innovate in each individual business unit and everyone truly wants to do what it takes to remain a leader in the industry.
Cons
As in most large organizations, politics can get in the way of productivity. It can sometimes be difficult to determine what is the top priority or exactly what your specific goals are as a result. Will they change tomorrow as the political battle continues? Overall, it is a great place to work. It is filled with passionate, smart, talented people. Things could be even better if everyone could truly unite around what is really important: the traveler.
