Revolut Language Owner interview questions

The interview was not with the HR person, but with a Language Owner for another East European language (because we are all the same, right? Pompous assumption and prejudice from the start). After passing it and wasting a day on their "homework" I was told I passed to the next level because they were really impressed with me and they scheduled an interview. One day before the interview, they cancelled it by saying "someone better accepted the job". Really? I was great at first and all of a sudden, "someone better" came in the picture? It was deeply insulting from start to finish and a total waste of time.
