My case is diametrically opposite. I can design anything and tackle just about any discipline. And my resume shows it.
Back when I was just trying to take a break from entrepreneurship and take a job for a few years I got no callbacks at all. Finally a recruiter took pity on me and opened up.
He said I had two problems. If I was dealing with a small company, one look at my resume and their would fear that I wanted a job to learn their business and become a competitor. And, at a mid to large company, when dealing with a VP or manager making the hiring decision, my resume would make them fear I would be after their job after gaining a foothold. So, he said "Nobody is going to hire you. You have no choice but to stay an entrepreneur or lie.".
Not long after that I landed a nice contract to help get astronauts to the International Space Station. That was fun and interesting...yet I eventually ran into the realty that they were paying 20-somethings about 1/3 (or less) of what I was getting. When my work was done my contract had nowhere to go.
Fuck me.
