Requirements of Internet companies for Android and iOS development engineers, androidios

Today, I spent the whole afternoon collecting online requirements from some famous Chinese Internet companies for the recruitment of mobile client development engineers, mainly Android development and iOS development. We collected about 10 leading enterprises in China. Because the new school recruitment is about to begin, I think these job requirements are still very helpful for students looking for work. I have sorted out the materials, and there may be some duplicates to make the information more complete. Students can learn according to their job requirements and will be more targeted.
