Questions posées lors d’un entretien d’embauche pour Account Executive chez Sigma Computing

I had three rounds of interviews - one was an intro call w/a person from the Private Equity company that funds Sigma, then the person that would be my direct manager & then the person above them. On that third / final interview, the person interviewing me logged into my Zoom interview 10 minutes late, with no notice about it. Then following that round would be an in-person interview, but the team totally just ghosted. No email response letting me know it wouldn't be a good fit or why, just completely ignored my emails. What a waste of hours of my time - very unprofessional.
