As someone who has been based in China for 13 years, and hiring for corporate clients coming into China for the first time, I can give you initial thoughts:
- Tell the client TIC - This is China Nothing will operate as it does in the US and you have to be flexible. Really flexible.
- Lower their expectations somewhat. International exposure is not that common in China for obvious reasons.
- China is like the internet, where no one knows you are a dog. In China no one knows that you are the biggest West Coast producer of widgets, or razor blades or car seats. A degree of humility is needed, and a great deal of hard core customer branding, marketing and selling. If you are on the ground in China you will have time, if not then it would have to more oriented towards hard core selling of the job, and the company. The worst thing you can do is assume knowledge of the company and go into that awful spiel about "So, why do you want to work for XXXXXX?"
- If you choose an overseas expat you will pay much more. If you go local you pay less but lose visibility. Your client needs to know this (not sure which side of the hiring fence you are on ..... )
- China is not one market but many. Your client needs to think this through because of the sheer scale of China, and the varying rates of development around the country.
- China has many myths but the biggest is that it is cheap. It was but is not anymore. Your client needs to know this because I have seen a number of companies fall into this trap.
There are a lot more issues but at least that's a start.
