As far as I know, game companies in Shanghai generally don't recruit interns. Generally, large game companies prefer to hire experienced veterans with high salaries rather than interns with zero salaries. Because they can't finish their own things, how can they have time to teach you to do things? They are not training schools, and they are even less willing to spend manpower and energy to train new people.
So my advice to you is that it will be more useful for you to find a formal training institution to study and then work in a game company. As for how to choose a good training institution, I have given many answers before. You can search "Choose a quality training institution with Bos experts to help you". I hope my answer is helpful to you, O(∩_∩)O Thank you.
