Is it true that for mechanical engineering graduates in Germany, placements in the auto industry require prior exposure to the auto industry for a Master's/Bachelor's?

Yes, prior exposure to the automotive industry is typically required for mechanical engineering graduates seeking placements in Germany's auto sector.

Most German universities expect students to gain relevant experience through internships or practical projects during their studies. For example:
- University of Siegen: Requires a 6-week industrial internship as part of the Mechanical Engineering Master's.
- RWTH Aachen University: Expects applicants to have completed an internship during their bachelor's; if not, an additional internship may be required.

Gaining practical experience during your undergraduate studies is strongly advised, as it fulfills academic requirements and improves your job prospects in the automotive industry.
