The last job I got from a cold ad was 22 years ago. I have had 9 jobs since then. Every one of them I got through the hidden job market (was never advertised) and through close people and direct contacts in my network. I never had any unreasonable requirements and I knew exactly whether my skills fit the bill or not after a 5 minute conversation.
If you want a good job, bypass HR and talk direct to hiring managers. The way to do that is to know someone who is hiring through your network. Yes. use your network.
Otherwise your just another number in the crowd and stacks of resumes and will never get past the HR screening unless your overqualified for the job and then you probably don't want it anyways because you will be bored.
