Pros
Booking.com really helped me to develop as a person and gain some great experience. I learned quite a bit and am very thankful for that. Great coworkers, nice benefits (commuter stipend, cell phone reimbursement, gym reimbursement, etc), amazing holiday party (BAM). Ability to meet people from all over the world working in different Booking offices. Great office spaces-awesome locations and beautiful. Fun events. Booking says they care about you personal development which is great-but check my point below.
Cons
Limited growth potential-after learning as much as you can, there really isn't much else to gain. LOW salary (very depressing). Managers definitely play favorites. Almost all of the managers I came across should not manage people-they are just managers because they've been at the company a long time. Meetings all the time. Booking says they care about your personal development, but actually don't care. Your managers will speak with you and ask you to improve every quarter. You have to come up with something new every time.
