My experience
Interviewed at Oxford Aviation in early January 2009 for LH seat B.737. I was notified of success in late April 2009 and started in Late May.
Things take time here in Nigeria.
As Tony says a number of folk are leaving for 'greener pastures'. Ryanair is a common destination though I have my doubts as to whether they will find the grass actually any greener.
