No, it's totally crazy.
A First Officer, whose qualifications might or might not be suitable - he was never assessed, he just bought the job. The PIC is going to be a senior commander, who will not respect the new guy sitting next to him for obvious reasons.
Two different cultural backgrounds and languages may sometimes lead to misunderstandings, especially in a stressful situation.
Of course, aviation is safe, and the Airbus will fly it's way. Of course the two guys will usually reach their destination.
But God help them if anything goes wrong. Again, usually things end up with a "close mishap" and get covered up.
But it's far from anywhere being safe.
