Denver Botanic Gardens Event Manager interview questions

Applied didn’t hear back for weeks. Got a random text that I originally thought was a scam but it was them asking for an interview. Had three interviews quickly on concession. The last and final round they had hr in the interview who went line by line on my resume and interrogated me. Never even called or emailed my rejection. I got a system automated message rejecting me from my phone interview when I was on the final round email. I had even emailed and talked to them days prior. Then nothing but the system message. Very unprofessional at the end.
