After all 80-90% of the questions were same as people here mention. In my case they asked a lot about my team work ability and opinion. Interview difficulty is average and all of the questions were quite basic. I wasn't hired because of my little experience and because I was not skillful enough (they didn't judge me until I get a final interview though) anyway you will definitely get hired if you show that you're skillful and a good team player. GOOD LUCK! "Why Booking?" "What kind of team do you want to work with?" "What kind of team you used to work with?" "What you like least about the team you have worked with?" "If somebody in your team dislikes you, what would you do?" "Why did you leave your last job?" "How would your family/friend describe you?" "Where do you see yourself in 5 years?" "Any suggestions about Booking?" (about translating and website contents) Also we discussed my language test on the first interview. "Was it enough to complete it in 2hours?" "How many extra minutes did you need?" "Any part you would like to rewrite?" (think and answer during the interview) "Why did you translate in this way?"etc.
