Booking.com Customer Service Executive interview questions

I have been called to talk regarding my previous employments by a very poor english speaker, asking generic questions like why i want to leave my current job, why booking.com and tell me about a time when you delivered great customer service, a question later repeated in the interview at their office. Once i have been invited into the office i have passed two tests, one for english and one for the language i applied for. The interview was your generic interview, same questions as on the phone plus availability. After they have simulated a call for me to answer and solve with my best skills.

Interview process included: online application and a phone interview. Online application was quiet intersting, but they have 104 personal questions, that can be pretty annoying. There were 2 language tests also.
