Can verify that there was no ATP in Nov. 2018, can't imagine there'd be one now with the experience level of the applicants. HR portion is very straightforward. No real technical questions, a couple of "So you're on downwind for such and such at such and such altitude, about how far out do you want to turn base?" type "see if you're a ringer" questions. Don't stress too much, if you're there, they want to hire you, etc etc.
