Production manager Andreas Peters subsequently congratulated on the anniversary and delivered flower greetings. 

In May 2012, Drobner started an internship in production lasting several months. He was able to prove himself as a reliable junior employee and became the first industrial clerk trainee in the IWN company's history.

At the end of his apprenticeship, he specialized in the field of operational control, to which he has remained faithful to this day as a controller of intelligent systems.
