Good interview, I genuinely enjoyed the discussion I had with my interviewer, and we spoke for 1 full hour. The negative experience, however, lies entirely with the HR who was extremely rude and unprofessional. I asked for an update a few days after the interview and specifically mentioned that even if I'm no longer under consideration, it's common courtesy to at least inform the candidate. The HR simply left me on read and never bothered to reply. I'm starting to believe that the negative reviews on the company culture were all true.
