If I could give a feedback, I would say that the interviewer should try to talk to another candidates on zoom, FaceTime, google hangout or other App that enables her to talk “face to face”. Since here at United States there are people from all around the world with different accents, these Apps make our communication much easier. Talking through cell phone was not a good option, although I had suggested to talk through one of those apps.
Furthermore, the interviewed should have a commitment with our time since she made an appointment to interviewer me but didn't call me on the agreed day
