Looking for a Voluntary Civil Engineering Practicum in Mannheim/Weinheim/Heidelberg – Need Help

Hi everyone, I recently finished my civil engineering studies, and I’m currently looking for a place to do a voluntary practicum (internship) in the field here in Mannheim, Weinheim, Karlsruhe or Heidelberg.

I’ve been searching online for days and have already applied to a few places, but unfortunately, I haven’t heard back from any of them. My German level is between A2 and B1, so I can manage some communication, but I’m still learning.

If anyone knows of any companies, offices, or even small firms that might be open to taking on a volunteer intern, I would really appreciate any leads or advice. I’m very motivated and just want to gain some hands-on experience in the field.

Thanks in advance!

And hopefully I get some recommendations :(
