I waited multiple months after my application. There were two rounds of interviews: One with a global internship regulator and the second with a country specific manager. The conversations were easy and there were no trick questions.

Interviewer was late, and took some time to read my cv while I was waiting to chat fluently about it, after a few minutes, she started asking some things about why was I interested in doing that internship, she was explaining the things that they were doing and the things where I could be helpful.
