Unity Sales Development Representative interview questions

Applied online, heard from recruiter almost immediately and set up phone screener. Easy 30 minute convo then moved on to interview with local manager. That interview was rescheduled once, and when it finally happened it went on for about 45 minutes and was again rather easy. I was told in that interview that I would be set up for another interview with another manager then have a final panel interview. The next manager interview was set, but was rescheduled not once but twice. After the second time the recruiter apologized and said this was abnormal and would reach out as soon as she had a date for that interview to be rescheduled for. Then I heard nothing. Absolute radio silence. I reached out to the recruiter and the manager I talked with and the recruiter straight up never got back to me. I finally heard from the manager that the position was no longer available. I was genuinely excited to work for Unity, but the process left a bad taste in my mouth. It was unprofessional to have two interviews rescheduled three times then never hear back from the recruiter about moving forward when I was promised an interview.
