Try a direct approach
Arik obviously prefer to use agencies for recruitment.
I work for Arik but have no direct number for recruitment.
Local folk who work for local airlines (i.e. Virgin Nigeria and ex airline Bellview) have approached Arik directly in person - successfully)
If you happen to be local it may be worth a try.
If you happen to live a few thousand miles away Arik may be impressed with the effort you have made.
Best of luck.
