One thing that might help (other than having code examples and/or CPAN modules that you wrote) would be to take Brainbench's perl certification.

That "certification" only proves you know very basic Perl. Everyone who has read any good Perl introduction can answer those questions.

I did that Brainbench "certification" a few years ago, and got Master level at it. Back then, I used Perl for only one year, and now I would certainly hire anyone as clueless as I was when I got my Brainbench "certificate".

Brainbench's a scam. I even got Master level at some Windows NT 4 administration thing and many other topics. All it takes is basic knowledge. I hadn't even used Windows NT 4 ever in my life.
