Perl software development is a seller's market, and that job ad is rubbish and fails to pique interest. It's a bland description with no indication of benefits or salary on offer. In fact, it's even less detailed than the crap Perl job ads that pimps spam me with me on a daily basis. Lack of detail implies there is little good to say about the job. Is that the impression you want to give?
Answer this simple question: Why the bloody hell should I quit my current gig and come and work for you? Then put that answer in the job description.
Uncertain fortune is thoroughly mastered by the equity of the calculation. - Blaise Pascal
