Shanghai is a great place to live
, however, working for Yangtze River I am not sure.
My personal experience with the place was not fun at all and I know of at least three more guys with the same scenario. I have PIC time from Oasis Hong Kong and they wanted to hire me as a B744 Capt then after I got myself to Shanghai they told me this was going to be for a cruise Capt then they could not make up their mind, by the way this all happened within 72 hrs. The HR Manager speaks no English, the chief pilot was never available, the rest of the people there with me were not as patient and some left. so make what you want out of this messy place.
Before you do the medical with Yangtze River make sure you really want to go to work for them because in China unlike the rest of the world once you take your medical with one carrier you no longer can go to work for another one unless you get release from them, this was not my case but one of the guys in the group decided to go with another carrier after taking the medical with Yangtze and the other carrier was not able to hire him because Yangtze will not release his medical. so another words they owned you from that point on.
hope this helps
