I applied online. The process took 4 months. I interviewed at Booking.com (Berlin) in Oct 2014
Interview
Usual questions. Prepare to perform a role play and language test (English + your target language). First everybody are sitting and listening to HRs. Then a short break, then group activities, then language test and afterwards an HR takes you to 1 to 1 interview (standard questions). In the end you are asked to perform a role play (HR describes situation (e.g. you are a CSE, and HR is an unsatisfied guest who arrived to the hotel). Read carefully all standard advises how to pass such a play and you will be ok.

Interview
Pretty fair interview process
They are always hiring so if you speak good English you have enough chance to get hired
The interviewer prepared a set of questions
I think she was still learning on how to interview candidates because she even difficulty reading those questions
I applied online. The process took 1 day. I interviewed at Booking.com (Orlando, FL) in Jun 2012
Interview
Very simple interview, they are not very selective as long as you are bilingual and they are desperate for employees who speak your language. They will test your language skills and let you know then and there if you get hired.
