Volocopter Engineer interview questions

Incompetent technical team interviewers. It seems they do not change their case study topic. After the interview, I talked with someone who interveiwed with the same team members/interviewers on the same case study topic last year. Here is a funny story about the interview (I was really, really anxious): -They asked me to make guess on a topic. -I said we would need calculations to make the guess -They said no, just make a random guess -I made the guess -They did not like it -I guessed again -They did not like it. ——-At the end of the presentation——— - I asked what was the answer to that guessing question. - They said, on the website we have the starting value for the calculations. :) - I said OK. (they did not let me do the calculation, they answered me with calculation :))))

The first thing was the HR interview. Everything was okay. It was a classical HR interview. After that, they sent me a case study. I presented that case study in a technical interview.
