Man, there has been some good advice on this forum.
As a fifty-something specialist/generalist myself, I fully appreciate how difficult it is navigating through a hiring economy obsessed with automated CV filtering, bullet lists and spotted unicorn recruitment.
But first, let me applaud some highly relevant material:
1) Thanks to ewozza who said you should present yourself as a specialist with a broad range of skills. DONE
2) Thanks to Don Jefe and others who said be true to yourself and find the kind of jobs you love to do.
3) Thanks to Pete 2 for providing a snazzy new skill-set to put on the resume.
MAYBE NOT! BUT I LOVED IT!
And although a bit off topic (well not really) read this article. It explores the differences between knowlege, wisdom and insight (experience is missing, but I couldn't find that link):
To apply a fairly simple example:
Knowledge is knowing what TCP-IP and the OSI layers actually are
Experience is spotting and replacing the frayed network cable that is helping pollute the network.
Wisdom is understanding how that frayed cable is just one small part of bigger problems in the client's infrastructure.
Insight is being able to succesfully design, recommend, market and sell a new network architecture and solution to C-level management.
All of the above resources are needed in our industry but some are very scarce. Figure out which one(s) the employer/customer needs and then pitch it. People with solid, broad generalized knowledge and lots of experience tend to rate highly on the wisdom / insight scale.
With 5000+ IT specialities out there, no one person can even list them all (let alone master them!). But anyone with hard-won experience, some balls and unafraid of hard work can hack through the jungle and find a job, even if it sucks sometimes.
Meeting the right people, marketing yourself and convincing contacts that you will provide better results than unicorn hunters and their recently hired unicorns is important. Remember that unicorn herding (PM or other technical management) is another useful skill, often overlooked.
You really need to go out there and sell yourself as a problem solver (not as a potential problem) and remember that YOU will have to make it happen. Mainstream hiring systems are broken and beyond all hope of repair. You must bypass them and find the people who are actually seeking value, as opposed to a risk-free existence.
