If you are looking for a new job - look at the negative reviews as it is a true reflection of the company - Mitarbeiter (anonym) bei Ground Control: Mitarbeiterbewertung

The overall culture is a major concern and, in my experience, falls well below what would be expected of a supportive and collaborative workplace. Management style can be inconsistent, and at times unprofessional. Following a disagreement with my manager, communication effectively stopped and I was largely ignored for around three months, which made it extremely difficult to do my job and contributed to a very uncomfortable working environment. There appears to be a disconnect between leadership intentions and the reality experienced by employees. While there may be a genuine desire at the top to build a positive culture, this is not consistently reflected in day to day management. Feedback shared in reviews like these points to recurring cultural issues, which suggests a need to reassess how that culture is being shaped and by whom.
