I asked the recruiter if I needed a presentation deck, but during the interview, the hiring manager asked me to walk through a case study, which clearly required a presentation. This was not communicated beforehand. Additionally, during the interview, the manager asked a team member to ask me a question, but there were audio issues, and one person did not respond. One teammember arrived late during my presentation and asked questions I had already covered, which I found rude and unprofessional. Overall, I did not enjoy the interview experience.
