Enriched Living Program Manager interview questions

Received phone screening and follow-up interview in-person at the New Brighton office. For my initial phone screening, I did not receive a phone call at the scheduled time. I had to reach out to ask the company why they did not call. We set up a time 5 days later. For the in-person interview, I showed up early and followed the instructions of ringing the doorbell. No one responded until 15 minutes after the interview was scheduled to start. They then were not in a hurry to begin. My interview started 17 minutes after that, a total of 32 minutes after the scheduled start time. There was no acknowledgement of the lateness. On top of that, I did not meet with the people that they said were going to meet with me. Overall, the interview felt incredibly informal and unprofessional.
