ServiceNow interview questions

They scheduled me for a presentation round with the hiring manager and two other org. leaders. Delayed other work to create the presentation but a few days before the meeting they requested to reschedule the meeting due to conflicts (no big deal- we all have challenging schedules). Provided recruiter future availability, didn't receive a response so I proactively updated availability for later dates. Recruiter responded that the hiring manager was OOO for those dates so she would need to get back to me. And then I never heard from the recruiter again. Ghosted by the company after failure to reschedule a meeting for the presentation round, post prep, for a leadership position. So incredibly unprofessional.
