I like it if candidates know about testing and OO. If they don't know Moose yet, that's fine. Catalyst and DBIx::Class are not something I would expect. Not everyone does web/database stuff. I don't, and I wrote a freakin' book about it!

It's a little odd if you know OO Perl but don't use Moose, but not a deal-killer. Honestly, I've found that there is a large faction of Perl programmers that refuse to leave the 1990s behind, and those are the people I don't want to hire. If you just don't know something but are willing to learn, then that's perfect. It's the "I will absolutely not use Moose" that == unemployment :)
