There really isn't an interview process. They do theses large virtual or in person hiring events where they just make sure to meet the educational requirements. No experience needed; you need to be able to pass a federal background check.

I went to the hiring event. The process took a couple of hours, due to the waiting, but If you passed the first stage regarding the resume, which was at least 2 years working experience, you were eligible to move forward. I had a 1 minute interview where he described the job and asked if that sounded like something I wanted to do.
