Concerning China. In 2012 I did the selection & sim for China Southern when they first stared recruiting. Although the sim wasn't easy, any Captain experienced on the equipment and with a few thousand hours on type would pass without trouble. That's the level of experience China Southern were seeking for their long haul expat Captains. If you could pass the sim check with a lesser level of experience, then so much the better for you. The rest of the selection was conducted very gentleman like. The problem I faced at the time was retirement at 60 yrs of age. Even back then, the money was very good.
