Honestly, I left the flying stuff off. I listed it as a job but with no description. However, if flying is all you have, you're gonna have to come up with something.
For the computer stuff, maybe you could describe programming the FMS?
But for anyone who wants to see some leadership experience, CFI-ing can easily translate into leadership. Specifically mention any programs you created/ spearheaded, pass rate, mentorship, evaluating, and counseling are all good.
It'll be tough to sell your FO experience. You essentially helped operate a very specific machine. Can't really sell management/leadership since you weren't in charge.
I assume you have previous computer experience? Your resume (and any others who have primarily only flying experience) will probably be best written in the recent college graduate style since essentially that's the bulk of your relevant experience. A work history is good of course, but it'll be really hard to translate a pure flying job into relevant experience an employer can sink their teeth into.
Good luck! I feel your pain, man - been doing the job hunt for over a month now and I know how arduous the job-hunt/resume/cover-letter/application process is.
