What is it like to work at Wellster?

Tough question. We’ve asked some colleagues to describe their experience with songs. Some of the answers were: Rolling in the Deep, Oh Happy Day, Show must go on and Eye of the Tiger. What does it mean? We don’t know, we just know that people love it here :)

What language do people speak at Wellster?

Official language of the company is English. We operate so far only on the German Market - so some people/departments must speak German. All the other languages are super welcome to join “the most prevailing language” contest :)
