I have just read the contract of employment forwarded to me by an engineer that was about to accept the position with mega oil.
Apart from the spelling mistakes and poor grammar, it looks like a good contact with a salary of 15000USD/Month.
2 things that really stood out was the fact they kind a discouraged the 28/28 rotation and promoted the bring the family option, then in section 11, The true Nigerian scam came to light, They wanted 20% of the total travel costs for the engineer and his family plus the costs of doing the documents for travel etc up front, As we all know, No oil company would ask for money up front for this kind of thing.
