3 video interviews + 1 case study presentation across 2 months The interview process wasn't too difficult, with behavioural questions mostly related to your previous experience. No red flag during the interview process: I was under the impression everything went well, but I wasn't offered the position because they were looking for someone who knew German. And no, no one had ever mentioned the language requirements: they brought it up after 3 interviews and the case study deck that I have presented to them.
