CFO Insights interview questions

Unprofessional, and frustrating. On the 9th I have booked a 15min interview at 10 am which was then rescheduled by interviewer to 12pm at 9.30am. This was already poor considering I had to reschedule past arrangements with 30 minutes of notice. Despite the inconvenience I agreed to the rescheduled time. I entered the Google meets room qt 11.58am and asked to be let into the meeting room. To my disappointment and frustration I wasn't let into the meeting room for the entirety of the meeting. This prompted me to email the two recruiters from the company I had contact with, but to no avail. Eventually I left the meeting and haven't till date received any substantial communication from either recruiters. Tldr - unprofessional behaviour shown by interviewer as I wasn't let into the meeting room by the interviewer for the entirety of the interview period.
