I'm suspicious of certifications in general and this one in particular. Never been able to understand why programming-language certifications are needed.

Will I hire someone w/o interviewing him only based on his certification ? No.

Will I hire someone who aced a certification but didn't show himself well on an interview ? No.

So what *really* are those certifications useful ? To get one's resume into my "invite to interview" stack ? No need really, as "excellent Perl skills" would be enough - the candidate would be tested on an interview anyway.

P.S: I guess that the easiness of cheating on these certificates makes them even less credible.
