based on experience and passing three weeks of class rooms tests,Drug test and background check,going to differents departments and seeing how the work is done and asking questions about the process of examining taxes

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.
