Hi Richard
From my perspective, I moved to Gib three years ago on the basis of a job offer received while I was working in the UK. I would not of moved here without a job to go to. However, I have met several people who have told me they moved to Gib without anything lined up and found jobs once they arrived.
I get the impression that the more specialised the work the more difficult it will be to find a job.
Be aware that property is very expensive here. We live in Gib because we have older kids and I didn't want to put them through the Spanish system and couldn't afford private education. Many °µÍø½ûÇøs live in Spain and commute into Gib for work. For an indication of prices look at .
Best of luck
Alan
