Something to note there is, how much attention is being paid to each listing. For the jobs you've applied and gotten, you probably were a really great fit.
Having reached a point of being on the other side, looking for people to hire, I think there are really warped perceptions all around. If your hiring, you aren't swamped with great candidates but with resumes. Basically, most resumes go in the trash, but because most of them are hollow, there was nothing there to start. If you're actually skilled and can demonstrate it in any way then its far easier to find a job. I think most of the people who apply to 200+ jobs to get one either are not skilled or don't know how to demonstrate that they are.
