It's not as good as these people make it out to be. Work is a bit hard to find right now compared to 2 years ago. The economic crisis must have something to do with it. Anyhow, beyond that, most of the offers are not for real. Often the wage your offered turns out to be much lower once you arrive. Then there is the housing issue, it's not always free. Don't deal with recruiters, be sure you are tlaking to the school directly, that simple.
