i had a similer problem, back when i did uni. i figured out a way to get around it. find a friend who has a business, or even invent one. now you dont have to make it a ralevent job, it could be cleaner, and your after store assistant what ever, but i have found that if you are employed, then you have a better chance. i sought work for about 3 months after uni. no go. dont make up jobs in your resume, coz it doesnt work, just make up your CURRENT job, so that your employed.
i got my sister (architect) to say i worked for her as a floor planner. ( which i had done during early uni, but not at the time) it wasnt remotly associated with the job i went for... BUT, because i was employed, i got the job. first time too. i think it has something to do with, if he is good enough for them he can work here, or lets nab him.... i dont know why, but its that way.
and remember to point out skills you learned through that job that related somehow to the one your after.
hope this helps... its not exactly honest, but considering your just a number on the payroll for companies, i doubt karma will care very much. oh and for the high and mighty out there who think its stealing a job... its dog eat dog, and providence is taken by the will...

I'm a sinner, yet forgive me nothing. I'm a heathen, but forever free.
