As far as I know, NOKIA does not recruit thru an advertisement such as this and gave their recruitment team by a yahoo mail.

What benefit they can gain from our CV? A lot!!! They can get our contact details and a lot of information. They can use your e-mail to send spam emails and others to mention. If Wissami you believe in this type of hiring, go on. You are free to do such.

And take the Nationality of this person if this is true.

Just a piece of my one cent advice.
