Ondaro System Administrator interview questions

I was contacted for a basic screening session with the recruiter shortly after applying. This interview went, to my knowledge, extremely well and I left it in good hopes. I was contacted a few days later with a proposed time and date for a second round with the hiring manager. I acknowledged that this time would work, and... nothing. I followed up a few days later because I never got a Calendly or Zoom link. Nothing came on the day of the proposed interview. Ghosted yet again! Or so I thought. The same recruiter reached out a few weeks later to tell me that they collected the feedback from the hiring manager and decided to go with other candidates. Feedback from what? The interview that they never gave me? Candidates take time off from work and adjust their schedules only to be treated like this, and it's commonplace at this point. Quit treating people this way, full stop.
