I make some research, izumi.org website exists, there was no spelling errors... so I decided to answer : I send CV and letter of motivation. Then always by email i receive questionnaires about my motivations it was called the "l'auto-entretien" - "self-interview" : I'am french. Again no spelling errors... So I continue and answer.
And finaly last week i receive a document called "Lettre d'embauche" - " hiring letter" from Abidjan with a lot of details (planning, salary...) four pages, and i was asked to sign and return it. It seemes too easy I thought...

I've make the answer that I'll not continue before seeing a "real person" and today i'am asking you if i can trust
these emails ?

What do you think about it ?

thanks

Scam, of course. Companies don't hire without seeing you in person. izumi.org has been around since 1999, scam sites usually don't last a year, but scams sometimes link to a real site to pretend to be real.

What job are they recruiting for? Could you post the hiring letter, with headers? (I understand French.)
