It is a very long process. You apply and usually call or get a call instantly for the first screening. If you pass you get a second call scheduled for later down the road. After that, you get scheduled for a face to face interview. This process is usually conducted as a mass interview with 50-100 prospective new hires at one time. This is pretty much just a formality as if you are there, you have the job, unless of course you do/say something to ruin your image. After the interview, you are directed to another office where you start the background check. Once you clear, which sometimes takes a few weeks as you need FBI/Homeland security clearance to work at the airport, you get an offer of employment.
