NextHealth (CA) interview questions

Interview was scheduled from HR to be first virtual; HR did not appear. After I sent an email inquiry; HR replied (after the interview was set to commence) that they could not make the time. After replying that each of the alternate times proposed (after HR had missed the first) were acceptable; HR stopped replying at all. Not exactly sure why; but it seems my experience matches most of the other interviewees insofar that NextHealth is a reflection of the current job market that employers can be this disconnected.
