Informal and formal by Teams with questions and sharing of previous experience; invited questions from me and wanted to know what I was looking for in the position; explanation of setting I would be going into

I had an interview scheduled with an employee. He emailed me the day of that he had a family emergency and wanted to reschedule. When I sent my availability to reschedule, he stated that he "may call me at 4:30pm". He did not call me. I got a text message a few days later to reschedule a phone interview for the next day. He did not call and I did not hear from the hiring employee again.
