Pros
Nice people, decent pay, good benefits, nice building in down-town Bellevue with lots of good restaurants around, quite a bit of "morale budget" get spent.
Cons
Right now (2011) it seems that Expedia as a whole (meaning many brands under Expedia Inc.) is struggling with direction and leadership. I believe Expedia will likely be a good place to work again in the future but right now, most people that I know would like to leave due to massive re-orgs, lack of leadership and lack of company direction. However, most people I know also feel that Expedia has good things to offer employees and would consider working there again in the future after the dust settles. Cons: Major leadership issues that trickle down to the lowest levels. Terrible cubicles with zero privacy.
