While you're waiting for the job opening, do some application preparation. You know you'll have to produce copies of a birth certificate, high school and college diplomas, certifications, and military papers (DD Form 214). Go make several sets of clear, legible copies and keep them in a file. Also make a PDF copy so you can send them as electronic attachments.
You'll want to avoid last-minute searches for lost papers and requesting overnight delivery of copies. Don't send a poor copy from the public copier machine with blurs and scratches. Produce a resume (just in case) with accurate information that can be validated. If you have a college degree, did you receive a diploma? Keep this document current.
Gather the information about your past work experiences and references. Face it, telephone numbers change and people move, so make sure to give correct information. Have all of the information on a prepared list to print or cut-and-paste—proper names, work and home contacts, and e-mail addresses. Don't use terms of endearment, use Snake's real name. Writing "Johnny D" as a character reference can send up a warning flag. You need to know how to portray this contact. Are they known from past employment, a friend, or relative? Also, be sure to ask them if you can use them as a reference. They could surprise you.
Don't alter or edit the application! Do you want to be a cop or a graphic designer? Applications are designed that way for a reason. The department got along just fine, and doesn't need you to change the fonts, type size, color, or add squiggly designs!
If you have to print it out to fill out the application, do it legibly! Take your time and ensure that it's readable. Watch the contractions, use only the standard ones. Use two-letter abbreviations for a state or degree. Follow directions and use black or blue ink. Some applications can now be submitted online; follow their recommendations.
