Hi Alpha,
Sounds a bit scammish to me for several reasons, but I don't judge a book by it's cover, so some may be legitimate.
I would generally stay away from things like that, because even though they make it sound like they will give you a job, they would not really "hire" you to write ads.
You would probably pay a membership fee, and they would provide information and support, and they will show you how to write ads (with your affiliate links)... so it's no different than doing an affiliate CPC business on your own.
I could be wrong... plus I don't like to generalize, so I would pay close attention to the details and terms, but of course you already knew that
