Global University Systems interview questions

I was ghosted after the first round interview, despite the recruiter saying that I was through to the second round. I sent a follow-up message on LinkedIn after the interview and then another ~2 weeks later. Both were ignored. If this is how candidates are treated then how are employees treated?

First stage interview. Interviewee made no attempt to settle into the interview spoke about being back to back all day, zero warmth, clock watching and didn’t not allow any time for any questions. The recruiter (junior) then asked for feedback which couldn’t provide because I had not had a chance to ask questions!
