Applying for Z visa but I'm under 24

Hi, I have been hired by a company from Shanghai, and I will probably stay in China for at least 6 months. I recently graduated from college with a Bachelor's degree. However, I am only 23 years old. The company that hired me already knows my age and most of my personal information. The company is also going to email me the documents to apply for my application. So will my age still probably be a major factor in my getting approved for a Z?
