TheQuietMan is correct is what he is saying about having to start your own business as the employment situation is grim, especially for new people coming to Spain and of course without language skills
I was recently looking for staff and was inudated with applications but the biggest problem is that it costs a lot to become legally self employed, wth everything around €350 per month before you earn anything and the cahnces of getting a contract job are very slim
If you do work ilegally on things like keyholding and property management you will face competition and legal established businesses ready and willing to report you to the tax people
For the airport jobs there were thousands of applications with preference given to local unemployed people, local jobs for Paramount are a long way off and the constructuon industry is in the toilet
The advice is that if you coming over and having to rely on work to pay your bills don't do it, you really need enough savings to survive at least 12-18 months, without needing to work and don't underestimate the cost of living
In my own case it took me 2 years of work to create a business that paid the bills
