I applied at the end of September, by the middle of October I got the invitation for the interview. Working fulltime, especially during the week it was kind of hard for me to find a suitable day for it, but my contact was very understanding and flexible so that we finally found a fitting day. During the interview we talked about how I would describe myself, and me fitting into the Job/Company. Most of it was held in german, but we also briefly talked in English. At the end of my interview they already told me that they want to invite me to an interview with the CEO. This interview was two days letter. Being slightly scared since it was one of my first interviews I was very nervous. Nevertheless, the interview with the CEO I had went well. About a week after I got the confirmation that I could start my apprenticeship there by the beginning of the next month.
Overall it was a very pleasing experience.
