u/Background_Turn739

I recently interviewed for a data analyst role, 1st round was HM, he seemed interested, scheduled PPT + Full Loop (4 rounds- HM + 3 others ) that also went very well. At the end of Loop another interviewer joined without any prior schedule or information and wanted me to walk through the PPT and many deep dived role based practical questions, he seemed very rude and felt he just wanted me to fail. I did not hear anything from HR for 5 weeks despite 2 follow ups, and recently received system reject. I was very hopeful of passing it.. but not sure what happened. Can i raise this that i was not informed about the last round?
