LFW - what am I doing wrong?

[Obi Wan]

I've been applying for jobs all over where I live and I can't get anything. The jobs I am applying for aren't rocket science but general shop jobs but I keep getting turned down. I have seven and half GCSE at C level, a AVCE Business studies at C level, and I.C.T Keyskills level 2 so I have a reasonable range of qualifications. I try to come across as friendly and polite by giving a smile when I talk to people, plus I give everyone I meet a copy of my C.V. At best I get invted to an interview but that's it, what am I doing wrong?

Thanks to both of you
