I think alot of the problem these days with getting suitable candidates is the use of CVs. In my day, for basic jobs you filled in an application form and sent it to the employer - now they want a CV and sometimes, even for intelligent people like myself it can seem a little daunting. You hear so much about how your CV has to be just right to get the attention of the people selecting but no one seems to point you in the direction of how to get it there. I work for the NHS and sadly if you don't have certain qualifications you don't even get past the first selection point. Not everyone has qualifications but that doesn't make them unsuitable for the job.
Sorry Dotty,got a bit off topic there - i totally understand your frustration though - if they are that rude to not even attend an interview who would want to employ them anyhow!
