My Dear,
I was called for same seminar but did not make it cos i was busy with my present work (Audit firm).
However,the money u were asked to pay should be made clear,is it after u have gotten the job and would b deducted from ur pay (if yes) how much u would be paid as salary?
If No, ask them how do they expect you to raise the money when u are lookin 4 a job,otherwise,u would have set a biz up n start on ur own.(this is just a negotiation skill whether they resort to the first option .
Good luck
