Generally speaking, applying for a Ph.D. in Germany pays the most attention to your master's degree and research plan, as well as the matching of research directions. Because Ph.D. is essentially a job, the tutor needs to evaluate whether you can enter a job quickly. It's important to make a good impression on the tutor. Don't wait for the tutor to ask for the research plan, but take the initiative to submit it to the tutor.

German doctors are more like apprentices, and tutors have great power to decide whether you can study for a doctorate or not. Before applying for a doctorate, you need to find your favorite tutor and send him your personal information and research direction. If he is interested in you, he will let you continue to write the research plan, and then confirm the research plan with the tutor and continue to submit the application.
