Many employers attach great importance to having a basic knowledge of the German language. Probably not all colleagues will be able to speak English. Therefore, think about improving your German on a regular basis right at the beginning of your studies. A good knowledge of German will also help you to get to know the local culture and to feel comfortable in the region and in the company.
The Language Center offers suitable courses in German as a foreign language for every language level. There are also job-related language courses.
You should also use every opportunity to come into contact with the German language. Take advantage of offers where you can meet Germans and make friends (tandem program of the Language Center, international get-together, (Internationaler Stammtisch) regional clubs, university sports, etc ...)
