Health Reserves interview questions

After the job was posted for less than 24 hours, I received a call directly from the Founder. Commented on my extensive experience and wanted to schedule a Zoom call later in the day. I waited for about an hour and a half with no email confirmation of the Zoom call. I go back to the posting only to find that the posting is no longer available. If I had to guess, my name and the sound of my voice may have altered him wanted to proceed with scheduling the interview. Very disappointing experience.
