In 2011 Spiegel Online published an article on how to write a job application for the American labor market. The beginning of the article points out differences between Germany and the US.
“Asking additional questions is not considered bothersome and the marital status should not be in your resume. If you apply at an American company it is easy to trip over cultural differences. Here is an overview over the most important concepts.”
After turning in your application, the article suggests: ”You should not expect that he or she will get back to you on his/her own.”
Conversely, asking additional questions is interpreted as annoying in Germany. The potential employer will get back to you on their own if they are interested. Asking further questions is considered to be obtrusive in Germany.
