The interview was very stressful and started with a simple introduction to the company's organisation chart followed by a case. I was given 10 minutes to read the case which was not enough at all, especially considering the fact that the interviewer interrupted me several times during that 10 minutes. Then I was supposed to present/propose a solution in front of an imaginary customer. The question/case was so general and broad, however, the interviewer sought exact and concrete answers. The question/case itself was not difficult, but the ambiguity of what it actually was looking for and the conversation atmosphere was very stressful and unpleasant!
