Congrats, sounds promising. My interviews were phone interviews as well. There were about 4-5 of them plus a driver record check and a criminal background check. This was the first time I had a phone interview, I found I was more comfortable than on zoom or in person.
Once they hired all the people they were going to hire there was a group zoom meeting for orientation and a website with some reading and tests for training.
I didn’t do anything in person until my first day of actual work.
