There was a tv series in the UK a year or two ago called ‘Bush Pilots’ about the fortunes of prospective pilots arriving in Maun. One of the pilots was a Ryanair 1st Officer with B737 rating and lots of hours who quit the airline to fly in Africa because his sister lived out there and she was very sick so he wanted to be close to her.
A lot of the companies in Maun were suspicious as to why someone would give up a decent job in an airline to come to Maun with no guarantees and they would not consider him. However he did eventually find employment, see the start of the clip below where he gets to do his check flight.

It’s quite an interesting series (about 6 episodes) if you’re considering the move to Africa.
Good Luck
