When you get to China do your very best every day. Make your questions count and focus on the quality of your work. Show your interest in learning Chinese and all about the company. In the end, only 1 out of 5 interns will be hired, but luckily not all interns come to China to be hired. Some come as a scholastic requirement, and others just use it as way to visit and explore China. So be sure to make your intentions known during your orientation and during the last two weeks of your internship.
You can also intern with a Chinese company if you like, but be super careful and check with China Scam Patrol to check the reputation of the company first.
