I currently live in the UK and at present on vacation in US visiting my Fiance'.
I understand your frustration of finding employment as it is very low and possibly 300 applications to a job and lucky to get interviews these days.... my friend always stated that "Agencies' are your best bet.
Just like paying costs to go to university... you get your degree but there is no job available in the line of work you require, things are going to get much "Tougher" as the Government are going to force many unemployed into voluntary work or loose their welfare therefore many companies may take on the unemployed rather than pay out a wage.
Both my Fiance' and I have been trying to make a decision who is going to move where next year, both sides have advantages and disadvantages but I will admit the UK is not what it was like 10-20 years ago and due to Government actions is going down hill. many expats who left the UK 10-20 years ago and wish to return to the UK in the near future will be in for a shock on how much it has changed and the Welfare support is being stripped from many people.
Try and get a job in
1: HMCTS - her majesty Courts and tribunal service
2: DWP - Department of works and pensions
Wish you luck on finding a job !
