The information is pretty right. I have also passed the screening on the second week of August. The ATPL is not a deal breaker, as they let you come back once to repeat it. You need a 70 or better out of 100 multiple choice questions (only a,b,c). The ones who pass do it with a 72 or so and the ones who fail do it with a 67 or 68, so it's all up to 4 or 5 questions. I was on the lucky side and what really matters is to study as many banks of questions as you can. Just google Chinese ATPL and you will find a bunch on the net. It's very similar to the FAA ATPL so the GLEIM book is definitely a good help.
In any case, everyone makes it to the SIM, weather you fail the written or not. They give you a SIM profile and they stick to it. It doesn't have anything you haven't seen before, but it is tiring as most of it is flown by hand on raw data (no FD's). You will do it on your present ACFT and they even let you use your own checklists and SOP's. 4 hours total (2 each). I did it on the B737 and I found particularly difficult the windshear right after takeoff. I firewalled the thrust levers and kept pulling up to the stick shaker and even then I was getting no climb. I ended up banking left and right to avoid the buildings and I thought we were dead, but at the end it started climbing again.
They also do "map shifting" for the SE RAW data ILS, which means that if you are spot on on the LOC, the magenta line on the MAP display will be left/right of the ACFT symbol which is contradictory and confusing. They really want you to ignore the MAP/FMC data and just fly the needle, which was difficult for me as it's something you never do on the line.
I won't comment the medical because you are in the hands of God. In any case you only receive the medical results 3 weeks after the screening (that was my case).
All in all, I personally received a very good treatment with high levels of courtesy. They paid for everything including all meals. It's just a bit boring eating noodles 3 times a day. We definitely appreciated our beers and a fat burger on the last day on an Irish pub, which seemed like an embassy to all of us.
My recommendation is not to get crazy with the ATPL as the SIM is the deal breaker. I don't think you need any hours on the SIM (I didn't get any). You just review the QRH for the events on the profile and keep your concentration high along with your courtesy levels.
Fire away if you need any further details and good luck to everyone...
