What is the best way to back out of a JB Hunt application.

Recently, I began the process of applying to JB Hunt. I filled out a pre-qualify form online, I completed a telephone interview with the recruiter, and I spoke to the person in charge of orientation. I received several emails, one of which was an authorization form, but I did not sign and return anything.

After reading the posts about the company on this site I decided that I should just stay where I am.

Here is my concern. Some of the posts suggest that they are a bit vindictive to potential employees who back out or are disqualified.

Are they likely to put damaging info on my DAC; and if so, how should I go about handling it?
