Selection process for free tuition PhD programs in Germany for STEM graduates

How does the selection process work for fully-funded PhD programs in Germany for candidates with a STEM background?

The selection process typically starts with identifying a relevant research group or program. Applicants, especially in STEM, often reach out to professors directly with a strong research proposal that aligns with ongoing projects. A strong academic background, often a master’s degree, is required. After submitting a formal application (CV, transcripts, and letters of recommendation), interviews assess research potential. Many PhD programs include funding, either through scholarships or research assistant positions, so ensure to check the funding details with the university.
