So lets say i have been Dq'd for little things like making a mistake on an application. If you are DQ'd from a few departments but in reality there is nothing on my background that should disqualify me then how will departments look at this?
Just don't keep making the same mistake and you should be fine. In all honesty you will probably have your work cut out for you and YOU WILL get grilled about this on the Oral Board and Polygraph.
would you mind saying what this hypothetical person made in the way of a little mistake on the hypothetical application?
