AVOID IT ...!!!
Oman Air is one of the airlines that you need to avoid unless if you wish youR aviation career to be end for good since they treat people very weird and you never know how & when will they fired you with no reason and end up looking for jobs everywhere.
they trusted in there flight instructors which half of them are really dumped
and the other half where not bad actually.
my advice to you is if you got any other option DO NOT consider Oman Air offer. If not then you have the choice to make your decision.
good luck
