Nobody on here can tell you anything you don't already know.
It's hard to get any job without relevant experience, I signed up to all the agencies after I graduated in July but didn't hear from anything in the sectors I expressed interest, basically finance. I've had a job as an accounts assistant for a little over a month so thought I'd change my CV on these sites. I did that Friday, and have had 3 calls and an e-mail today. All these high street agencies look at is your last/ current job title, if you don't have the one they want you wont get a sniff. It now seems the second tick needed is a car :|
