Uber Product Operations Manager interview questions

Was contacted via email 3 days after my initial application for the role and informed to pencil myself in for an interview based on Interviewer's availability on Calendly. Sent a chaser email to thank the Interviewer and indicate my looking forward to it. Interview was scheduled for 10 days later. Waited 45 minutes in the meeting room for said interviewer to show. Had sent a reminder email after 5 minutes and then a follow-up after the entire period. No follow-up, tried connecting on LinkedIn, no response either. Was completely ghosted by the organisation. Happy to provide proof of communications if necessary.
