Vantaggi
I waited nearly a full year to write this review to make sure I could provide feedback without rose colored glasses. In gernal, I love working at Expedia. Expedia has a good work life balance. Most individual contributors on the tech side work around nine to ten hours a day. On average the work force is younger, friendly, and intelligent. It is rare to find a team that isn't open to new suggestions or unwilling to try and find creative solutions. It is also possible to work from home occassionally if needed. The travel discounts for full time employees are great. If you love travel and technology, the tech side of Expedia is a great fit. If you don't want to travel, you'll miss out on some of the best perks.
Svantaggi
Like any company, there are those teams which are the exception to the rule. My advise to potential candidates is to ask how many weekends the team works on average each month. Most teams don't work any weekends, and the teams with severe issues freqently work long hours and weekends. The pay scale is not as high as Amazon, and slighly behind Microsoft. There is also the odd manager who puts himself ahead of the team, but movement between teams is fairly straight forward.
