Finally the called me today from a withheld number asking me to answer asap for this job.

Should i be worried about the info they know about me? What is their profit over this scam?

Thanks,
Fotis

Fotis, Whilst it is too late to retrieve the info you have sent to the fraudulant person, try not to worry too much. I too sent private information to a scammer previously and have had no adverse effects.
You will need to put it down to one of lifes bad experiences.
What is their profit over this scam?
Had you continued to have dialogue with the scamming trickster, you would have been hit with imaginery, concocted fees and charges that needed to be paid by you. It would simply go straight into the scammers pocket. Also the fraudster may, or may not sell your email address to other scammers. There is a chance you may receive other scammers writing to you in future, hoping to lure you in to their web.
