I called the foreign ministry in my country and they advised there was no remarks on Sierra Leone. Certain places you were advised not to visit, but not different than any other place f.ex Johannesburg.
Cost of living would be in the area of 2-300 US$
pr month if company provided accomodation, transport etc which I was informed they would at the interview.
It is one of the most poor countries in the world, very beautifull beaches.
Apparently long lay-over's in London, Paris, Amsterdam (on the Airbus) with good
pr diem.
Did they advise you of any startdate for operation ? Date of flying to Sierra Leone before operation commence ?
Cheers
