Booking.com Customer Service Executive interview questions

Online application process took me over an hour to complete. After few days I received an email from the recruiter to schedule a phone interview. The lady really liked me and was happy to invite me to the office for a group assessment and another interview with two other company members. I've been told I am one of their favourite candidates. Unfortunately few days later they called me and said they didn't like the way I've done my role play. Well... After all these compliments and the long process they are telling me that this was the only reason I didn't get the job... And I've been told I can try again in few months. I'll pass.
