I am a graduate student in a university in Shanghai, majoring in optical engineering. I still have one year to graduate. How to prepare for Master Philips?

You can look at the recruitment requirements of Philips in the past few years, focusing on increasing your practical work experience, and then your English ability. These companies are interested in ability, especially those who just graduated. It is important to have practical experience. When interviewing in a foreign company, I didn't ask for professional knowledge at all. So, what they are interested in is your comprehensive ability and quality.
