Self Assessment

I'm in the midst of a most interesting Memorial Day Holiday weekend . It started with my resume on the internet. It's been floating around in cyberspace since my layout from Honeywell Aerospace in 2010.
I received a call from a recruiter a week or so ago asking if I'm still actively seeking employment. I explain to him that I'm currently working but that I am always seeking an opportunity to better my position in life. He seems genuinely impressed by my answer. He goes on to inform me of an e-beam welder (electron beam) position that's open in So-Ca, El Cajon, California to be exact. El Cajon is a small ageing city in the hills just east of San Diego.  It's just shy of five hours from my current home in Maricopa, AZ, two hours from Yuma and ten minutes from the beaches of San Diego. Oh yeah, and has absolutely perfect weather.
The recruiter is seeking a candidate for GKN Aerospace, a manufacturer of turbine engine components for both commercial and military aircraft.
This recruiter starts going over items listed as competencies in my resume and asking for clarifications of each. He seems satisfied that I do indeed have the skills necessary to forward my resume on to GKN.
Fast forward to this Memorial Day weekend. GKN Aerospace wants to see me face to face and have me demonstrate my tig (tungsten inert gas) welding abilities.
What? I haven't welded on the bench in years. I'm pretty sure I still can, but to demonstrate in a certification test type environment with no practice, that's a scary thought.
Now I'm starting to think about those competencies I claim to have. Am I really competent in these skills or are they just a list of jobs I once did years ago?... Well it's time to find the answer to that question.
