Pros
Expedia Inc provides an opportunity to work for one of very few successful .com companies - and there are now dozens of lines of business and points of sale within the EI family, so there's lots to choose from. The work is frequently fast paced, and there are opportunities to innovate.
Kontras
Unfortunately, Expedia suffers from a highly dysfunctional communications structure - not only does top management not talk to employees, frequently members of the top management teams don't talk to each other, resulting in lack of alignment towards goals, and duplicated or contradictory work. The Expedia culture has also shifted towards a dramatically more top-down decision model, which doesn't always sit well with employees who were often hired to think and act entreprenurially.
