Pros
There is a great culture of learning at KAYAK, where you are going to be tested not only for your knowledge, but also your ability to adapt and learn new things. The company still retains its startup vibe in a lot of places, with a mature systems and processes environment that lends itself to stability.
Cons
There is the familiar corporate ladder that one needs to climb, where you encounter people who are either insistent that you're not ready for the job, or simply prefer someone else. A lot of your success depends on how well you manage your relationships with people, and whether that person likes you. There are folks in leadership who seem entrenched in their roles, and thus stuck in their ideas, unwilling to explore or be educated. Although the senior leadership is receptive to feedback, frequently it doesn't feel like there is traction to what one encounters in their operational role at the end of the day.
