You have a serious attitude problem. The moderators removed the vile insults you hurtled at me half a day ago, but that seems not to have deterred you in the least. Here you go again today, embarrassing yourself even further. You know nothing about me nor my qualifications, but have already passed a verdict about my odds of landing a job in ShenzhenYou have yet to provide any "facts" buddy. I didn't write anything that would or could be considered childish; what I have opined based on my personal, professional experience simply informs you that your qualities, qualifications or lack thereof would not be at all an asset for any Chinese companies in China. You don't know the language, unfamiliar with the culture other than the bastardized, caricature version of my culture.
I work at a high tech multi-national where half the employees are expats, most of whom don't speak a word of native language nor had the faintest clue about the local culture before immigration. FWIW, the largest expat ethnicities are Chinese and Indians. Yet we consider all of them valuable assets and indispensable to the success of our company, which btw would be the envy of any company in Shenzhen.
Are you saying that all the expats desiring to work in Shenzhen at a high-tech company need to prove their proficiency in reading and writing standard Chinese before they would be considered eligible, say for a mechanical engineer or data scientist position? I've read the Analects and several other ancient Chinese classics. Would that improve my odds to pass the cultural assessment part of my job interview? As for technical qualifications, I have a PhD in my field of expertise and +5 years of experience. Not good enough?
