TL;DR: They ghosted me.
I applied and was emailed within a few days to schedule a phone screen for two weeks later.
A couple of minutes after the scheduled call time, my contact emailed me to say that my number was out of service (it is not; I had full bars at the time, and I checked to confirm that I had provided my correct number in all relevant places). I replied immediately to confirm my number and to ask if there was a number I could reach her at instead.
I waited for over an hour but she never responded.
I understand that technical issues or mistakes happen, but it really felt like my time was not respected. It was a disappointing experience.
