Is there really an AGR interview/board you will have to attend to be selected?

I came onto the program september 2018. There was no interview, i assume they performed a review on my iperms to insure my I's were dotted and Ts crossed. Was just the application on hrcapps, a job offer, some more documents filled out and submitted, duty station offers, orders cut and out the door.

Negative SGT Sheedy, only the national guard has to do the interview process. You will need copies of your most recent NCOER's though. If you have any more questions just PM me.

To apply you submit a digital packet. The packet gets boarded and you get put on a list (Tier 1-3). As positions open up for that year, they pull from the boarded list (in addition to rank and MOS).
I was on the Tier 1 list the first time I applied, no positions were available so I didn't get picked up. The next year when I applied (yes, you have to apply yearly), I was Tier 3 and didn't get selected. I've moved on but that is how I recall the process.
