Comment Volunteering did it for me (Score 1) 128
No post-high-school education here, but spending insane amounts of time beta testing, packaging, proof-reading documentation and generally getting my hands very very dirty with one particular Linux distribution landed me a job as a packager/documenter with the distro, and last month I "celebrated" my 8 year anniversary working with the same company (now working on security).
The thing that got me in, besides obvious skill, was the volunteer work and passion I put into the company so the end result was they gave me a cheque for doing in an official capacity what I'd been doing unofficially for months.
The nice thing about that is that it gave me the time to increase my knowledge and skills and has gotten me a number of minor little projects under my belt in that time as well as two significant projects (both more or less defunct now, but that's besides the point since both projects had more value to me in terms of what I learned by doing them).
