Yes, I live close to Frankfurt.
The first interview with Japan Airlines was very relaxed. First you have a written test, where you have to answer 4 questions (Tell us something about you, your family and friends/Tell us something about your experience in service/Tell us something about your strong points and weaknesses/Tell us something about your hobbies and interests) After that you have the one on one interview. And there they ask you the typical questions like everywhere else. The JAL staff was very friendly! I am excited to see how it will be the next time. I will let you know how both interviews went.
