AstraZeneca Director interview questions

HR screening, then set up with HM for a videoconference. Standard procedures. But my scheduled videoconference never worked. After it was set up, the conference link has no actual testing. It seemed good to go (I can join in, and waiting for host appears). In the actual interview, it kept rejecting me joining in. So I have to rush to work with HR rep to generate another way. After 10 minutes, it finally connected me with the HM. But the HM seemed pissed off, and the interview ended in 3 minutes with she propose to reschedule, which never happened. I didn’t hear a thing from anybody afterwards. It is surprising to me that how by unprofessional both the HR and HM were.
