Was scheduled for a phone screen, it was cancelled 10 minutes before and rescheduled for a week later (through a bot). Today was the rescheduled time and 8 minutes before I received a message saying, "Due to unforeseen circumstances, your upcoming interview was cancelled and we are therefore no longer able to move you forward in the recruiting process. Please reach out to your recruiter for additional details." Seems pretty unprofessional to me. I even emailed the person I was supposed to be meeting with to make sure the reschedule was correct and got no answer.
