My experience is very similar to yours. I haven't responded to as many jobs.perl.org postings as you, I'd guess around 25 or so. Like you, my qualifications were a good match for the requirements, in some cases an exact match. Number of replies I've received: zero. By replies I don't mean job offers, I mean requests for more information, "we'll get back to you", or even "Thanks but no thanks".

I assume this is because the pool of qualified applicants is so large, but I also wonder whether all of the postings on jobs.perl.org are really seriously looking to fill an existing position.

I'm convinced, however, that job postings on jobs.perl.org remain long after the position is filled. IMO they should expire within a set period like two weeks unless 'renewed' by the person or company advertising the position.

I hope to hear from more monks about their experience with jobs.perl.org.
