Hi, it seems like many hacker jobs are obtained via personal connections (either directly or indirectly), and that hit rates on applying online to job posts are pretty low (especially nowadays).
If you've gotten your current (or past) job without any prior connections, what kind of job was it and how hard was it to get?
The cover letter is the most important part of any job search. In mine I explained my side projects that I work on and my insatiable love of learning new technologies. I was up front in both cover letters, stating that I had no experience in the language they were hiring for, but I have a verifiable track record of being a quick learner when it comes to technology.
