For my experience of an interview, I was texted at night and asked if I could talk. Since they were willing to hire everyone it kind of felt like a gauntlet, wouldn't surprise me if bets were taken place, to see who could make it. There was nothing professional/instructional to being hired on. After your application you come in with a group of people and spend a little less than two hours on a computer answering questions on videos you just finished watching. That's it!
