Ability Network Project Manager interview questions

The interview call was scheduled, but I had technical issues with my phones. I had requested to be contacted via landline. HR Recruiter tried to reach me through my landline and mobile, however, I didn't want to pick up my mobile phone due to so many spam calls I have received (I just got this new number 2 months ago and already bombarded with several robo-calls and debt collectors for the previous owner of this number) so I sat by and waited for my landline to ring while letting the mobile phone go off. After 3 minutes, I received an email letting me know I couldn't be reached. I immediately called her back several times, left voicemails, and wrote an email explaining my situation. She didn't pick up and finally responded to my email the next day to reschedule. She never showed up for the rescheduled time nor the one after.... Very unprofessional! This to me is a bad representation of how the company treats employees. if the HR recruiter can't get it together...
