First I had to go to the local zoo where they were having the interviews. They for whatever reason had planned to show a movie that was scheduled to rune only at certain times, then make you wait to be interviewed in one of several lines. I was on lunch, so I couldn't sit around waiting, and I had to ask a few different people could I just get an interview since I'd already submitted my application. Most said 'no, I had to wait'- but one person got me past the bs and I only had to wait in line, get my interview, then go home.
Then wait for a response, which took a few days, then wait to be scheduled for a phone interview with the client of the program I was applying for. After that there was more paperwork, a drug test, and then more waiting. I think the total time was about 3 weeks from application to hire.
As an aside I asked other workers once hired about their interview process & it varied wildly, so 'Good Luck'?
