I was referred by my friend, so skipped the HR interview so did virtual interview with the Controller for 45 min. Very nice conversation, mainly asked about my previous work experience

Set up an interview with a HR person for 2 days later. Day of interview arrived, 30 minutes went by, no show. I made repeated efforts to email the person and didn't receive any response. Extremely disrespectful and unprofessional to not give any notice or any apology. Safe to assume they ghosted me, which I haven't experienced up to this point.
