I'm currently studying in Germany on an exchange from my home university, my scheme consists of 6 months studying and 6 months working in an internship. I applied online through the Daimler website and was asked to go for an interview (just email), I of course emailed back and went to the interview as planned. The interview itself was not very hard at all, in fact it was quite pleasant and I really enjoyed it. I received an email about 3 days later saying there weren't enough English only roles (I speak a little German but that's all) and to contact someone else who's working on English projects, I contacted the person who they suggested and got invited to another interview.
