Interviewed with the team onsite and it took 2 weeks. There was a presentation that was required for a case study. The presentation feel on deaf ears primarily because the hring manger became confrontational and criticized but she appeared very insecure and she didn't read her own case study as presentation reflected the case but something above her head so she lashed out vs. asking intelligent questions in a professional way. The others were very uncomfortable. This is a red flag big time. Role was also a new role too so seems the candidate & case study are experiments until further changes are needed.
