You will be interviewed once or twice depending on how much your interviewer likes you. They are looking for dedicated people who will do whatever it takes to get the job done while utilizing common sense and best judgement. You will need to apply online multiple times because applications are often selected at random, due to the fact it is impossible to read every single application that is submitted. I submitted four applications before I got a call. You will then get an interview and if you pass that you are in good shape. The background packet is the tricky part it goes more in depth than some law enforcement agencies. You need to respond to your background investigator immediately. If you cannot reach them leave them a message and always ask for confirmation that they have received your documents. They receive so many faxes at the H.R office that they often times will not look for it unless you ask them about it. It also shows dedication to working there which is what they really desire.
