If you were my little brother, and you told me that you had applied to 100 jobs you were strongly qualified for and got zero offers, I would put on my big brother pants and make some fairly pointed observations about your skills, beginning with lead qualification. I would then advise working on skills like lead qualification over sending out 100 more resumes into a process which, as your big brother who loves you has…
What do you mean by "lead qualification"? Searching Google wasn't helpful...
For example, I consult, and while in principle I could attempt to sell anyone with authority to write a check on consulting engagements, I don't. If I meet someone at a party and he says "I don't have a website but..." there is no possible end to that sentence whatsoever under which he is a good prospect for business in the near term. If you want a Rails programmer? Nope, sorry, I'm probably not your guy. If you're a software company with $10k in the bank, you can't afford a formal engagement with me. Strongly qualified leads for me tend to, e.g., have over 10 employees, profitable software businesses with revenue in the millions to tens of millions, multiple opportunities for things I can do for them, a business model which suggests ample opportunity for positive ROI at the rates I charge, and some reason to have personal trust for me.
To the extent that I do active sales work (e.g. flying out to a city to meet with your CEO, creating proposals, etc), I focus my active sales work on qualified leads, rather than "any business I could possibly think of."
Applying this to a job search: he's sending resumes to places which are not hiring. That isn't a strongly qualified lead. That's like me soliciting five figure checks off every passerby in Ogaki Station. Total waste of time.
