In my experience in trying to find a job, I applied for so many positions that I was extremely qualified for, only to never hear anything back, or 'don't call us, we'll call you'. I have strong qualifications in my field, but didn't have any UK work experience, so had to take a low-paying job just to get by. Once I had that first job and was able to list a local reference, I was able to get another, better-paying job, but if I hadn't been allowed to take any employment that wasn't deemed 'high-skilled', I would have had to leave.
