Purple Perfect interview questions

Had a virtual interview scheduled for a weekday afternoon. When I attended the interview, the interviewer wasn't present. Waited for 15 minutes, sent him a reminder email and continue waiting. 10 minutes later, his assistant called to tell me the interviewer is on emergency leave and rescheduled to 2 days later. 2 days later, interviewer showed up but no apologies whatsoever for last minute reschedule. Interview itself was unremarkable. Didn't get an offer. Even if I did, would've declined cos who'd want to work for someone who doesn't respect other people's time?
