I know this has changed since I got hired, but it was a lengthy process. I applied 2-3 months prior to getting an interview and it took another few weeks to get a job offer. At the interview I had to fill out paperwork, complete a spelling test, typing test and reading comprehension test. The tests were a joke at the time. It was a simple word document that could easily be altered in your favor. The interview took about an hour as it was 2 different interviews, one with HR asking basic employment questions and if you advanced there was another panel of several people asking questions and writing answers. The whole interview took a majority of the day.
