Tidyquant interview questions

There were three people who took the interview. After two pretty time taking assignments there was this interview. One person was respectful but the other person was obnoxious. The interview went on for 1:30 hour. Worst thing was after all this they did not even care to inform about the result. When I confronted about it the HR said it is okay now you know the result and what could you have possibly done with the result when you were not even selected.
