I was booked in for a phone call interview that never took place. No one contacted me to let me know the meeting had been rescheduled or cancelled. I reached out to the person that was supposed to be speaking with me via LinkedIn (I hadn't been given any phone/email contacts to reach out to directly), but didn't get any reply. It's really poor form to ask me to sacrifice my time for an interview and then not show me the courtesy of even contacting me.
