They contacted me via a teaching site and asked me to apply for a position. I set up a phone interview, at their request. No one contacted me at the scheduled time or responded to my outreach. The next day I got a form notice that "after further review" I did not suit their needs at this time, and apologizing for the "misunderstanding". I found it extremely rude and unprofessional to have my time wasted in this manner--if I was not a suitable candidate, they should not have asked me to schedule an interview, or should have at least had the basic courtesy to have cancelled it beforehand.

Easy, very straightforward. Was virtual because of the pandemic. They got back to me within a couple of minutes. HR was very supportive. They were straightforward with the information I needed before the interview.
