The whole process took over 2 months. After I applied, I got an answer the next day. First, I had to do a video interview (my first experience with an app like that - I felt very uncomfortable), 3 weeks later, when I did not even hoped anymore to get a feedback, I got a phone call which turned into a phone interview - a few questions about myself and a promise, that they will get in touch with me soon, 2 weeks later I got an e-mail about a skype interview. It took another week to get back to me. After the skype-interview, which was with a very nice German guy, I waited another 2-3 weeks and finally got an invitation for an onsite interview. After another 2 weeks I got an e-mail that I was not successful. The disappointment was even bigger, because I had to go through so much things. But it was an experience.
