Went to an interview once with a British company to fill a slot as captain on an ex pat contract in western Africa. Towards the end of the interview I asked if the first officers would be nationals only to be told that there were no first officers, only captains and commanders. All pilots were ex pats. Insurance requirements were so high in that part of the world that no real first officer would have met the standards required by the insurance companies. Therefore the company was advertising for experienced pilots who were already captains to work in Africa, live in a compound and fly as first officers with commanders.
I found the description of work and living conditions to be distorted and not very conducive to sane and structured operations.
