It's more likely your friend won't be able to find a job in EU because if he doesn't have the right to live and work inside EU, it's almost imposible to live and work here.
The position is more likely to be obtained by a EU citizen. As the other way around, a EU citizen has the same difficulties if he/she wants to work outside EU (needs a VISA) so it's the same problem. I suggest you try to find something for your friend in Turkey or near, it's not posible for non-EU citizen to find a job in EU.
Same happens if you want to go to USA, much more difficult to get a VISA to work there.
