I have now been contacted several times by recruiters in Germany and their behavior irritates me.
First I need to explain that there are two different modes of addressing someone in Germany (and I suppose some other countries have them, too).
The first one is formal and neutral: You call him/her "Herr/Frau surname" which can be translated as "Mr./Mrs. surname". "You" is in German Sie. This is used if you do not know the person personally, if you are making negotiations and it is also a sign of respect. It helps to maintain professional distance if a deal busts, if a conflict arises etc.
The second one is more intimate: You call him/her by their first name and "you" becomes Du. It is reserved for people having a close relationship with you (parents, siblings, your SO) and people who are in frequent contact with you (colleagues, acquaintances and leisure contacts).
The recruiters in question now used the second form to contact me. The first one even continued to address me in the second form after I answered politely in the first form (hint, hint). The whole form of the letter was also in a form like we were long-time chaps and I admit that it felt borderline manipulative (You know those guys which get chummy very fast and, surprise, want a small, little favor from you). All were from recruitment agencies.
I am now a little older (40s), but from the viewpoint of someone working in Germany:
Is it now acceptable to be addressed in the intimate form? I know that the tech industry is more informal, but would you accept to be addressed in this way in a first contact mail? If not, do you know why the recruiters are doing this?
ADDITION: If there is a misunderstanding: I am not talking about the interview process inside a firm or recruiters from the firm which are searching candidates, I am talking about recruitment firms like Hayes etc.
