Pros
The people the people the people. Every day that I get into work, I'm blown away by the great people that I work with. We have people from all walks of life that band together to bring success to Booking.com's collections. The current management team provides every opportunity for personal development and encourage out of the box thinking. This department isn't for everyone though - if you are slow to adapt and unwilling to work as a team, you may want to look elsewhere. Negative reviews on here for this department likely stem from those who were not quick to adapt and outwardly talked poorly about their colleagues. There are often travel opportunities that take you all over the US and Canada, even overseas to Amsterdam. There is an onsite gym, 401k matching, and fresh fruits and vegetables every day. There are many other pros, but if I started listing them, I'd likely never stop.
Cons
The HR team members are rarely on the same page. I've had multiple instances where I receive one answer from someone and the complete opposite answer from another. There is an obvious lack of support and no one really seems to know what they're doing... it causes for extreme frustration for everyone. There is also little room for growth, if you assimilate growth with promotions. However, there is plenty of opportunity for personal and professional growth that can help you set yourself up for future promotions.
