I think that might be the main difference.<p>I worked in Germany and in the US.
The only time that recruiters got a tad annoying was when I was working in Germany and got 2-3 UK agencies.
By far not as bad as the post makes it seem, but some slightly annoying things such as calling me on a Sunday evening, trying to give me prep speeches and overusing my name, script reading, trying to not tell me the client name, mispronouncing the skills they were looking for, ...<p>In the US, the recruiter eMails are more frequent, but usually pretty civilized.
Especially the bigger companies (Facebook, LinkedIn, Google) that have their own in-house recruiters tend to be pleasant to work with.
