Applied via LinkedIn and was scheduled a phone interview roughly 2 weeks later. When the time came for the interview, I received no phone call and waited over 20 minutes. When I emailed the interviewer about this she claimed she called and got only voicemail despite me having been sitting in front of my phone 30 minutes before and after the agreed upon interview time. I also went over our past emails to check that the correct phone number was sent to make sure that I didn't send the wrong number, but it was correct. She then said how she was booked with interviews for the day and that I would have to reschedule. I replied apologizing for the inconvenience and asked when she would like to reschedule. I got no reply. Very unprofessional.
