I applied online. The process took 2 days. I interviewed at HOLUB, STEINER + PARTNER (Bochum, North Rhine-Westphalia) in Apr 2015
Interview
Skype interview with a nice lady, nothing very complicated. After filling out a form they invite you for an interview via Skype with other applicants at the same time. Interviewee is very nice and open minded, always wants to know as many things about you as possible.
