A personal interview is not uncommon even in case of internships. Since it’s simply impossible for applicants from Maghreb or Levant counties to travel to Germany for an interview, it’s important to ask in advance whether it is possible to have an interview via Skype or another video chat channel. More or less all HR officers will understand that. However, a “distance interview” is not very different from a personal one.
Appear in person (HR officers are professionals. They realize if you try to cheat them.)
Appear in time. (i.e. 20 minutes early)
Be well-dressed. (Not overdressed. You must not be the best dressed person in the room, but not the worst dressed either. Unfortunately it is impossible to give further hints here, since dress-code depends very much on the type of business.)
Be well prepared. But do not try to memorize standard answers. HR professionals know all the standard answers and might be bored. Try to be yourself, but be specific, factual, technical and realistic. The topics you have to be prepared for are: details of your CV, details about the company / department at which you apply, your strengths and weaknesses. Latter is very common and very difficult to answer. Don’t be too shy; don’t be too self-confident. Don’t try to lie. The recruiters know that everyone thinks that impatience is a “positive weakness”.
