What have been the best resume tips you have received for transitioning to civilian jobs?

I would recommend all Veterans to get on LinkedIn and request the Premium Package. After that there are Groups you can link in with. A great group for Veterans is Veteran Mentor Network. It has a site admin that will answer all your questions and link you in with other Veterans. But this is question about resumes, right. This is where linking in and networking will help you in your job search. You will develop several resumes in this process. You may have a Master Resume and you may have a resume for the exact position you want with the company you want. Linking In with other Veterans that have transitioned that can read your resume and guide you thru the editing process is invaluable. Last tip: You will not know how to write a resume. The Federal Resume process is another topic for gnomes and unicorns lucky enough to ride the GS train. Resume Tip: Use Glass Door, Indeed, Monster and others, to look at open jobs and other people's resumes. Also, start tracking all the jargon or keywords. The resume is just phase 1 to the Interview Process which can be a 30 min phone call or an in-person interview.

Create accomplishment statements. Accomplishment statements are the core to any resume regardless of it is chronological, functional, or of a hybrid format. Accomplishment statements should be written using the CAR (Challenge-Action-Result) format. The statement need not be written in that order, though. If possible you should always start with the Result. These statements will demonstrate what you actually do in a quantifiable way.

For example: Improved service call response time by 30% through the creation of response guidelines and revision of troubleshooting flowcharts.

The Challenge in this scenario is that it is taking too long for initial response to service requests. The Action was the creation of the guidelines and the revision of the flowcharts. The Result is the 30% improvement.

While I plan on staying in my current job until I retire, I continue to add to my list of accomplishment statements which is up to about 65 or so.

Honesty, if you add a bunch of BS it will eventually come to light and bit you.
