Thank you, but beg your pardon, YMMV?

I agree with your summation that of course the specific knowledge relates more or less directly to the proposed job and it's responsibilities. You did however stumble into the grey area that is rather plagueing me regarding the subject that is 'I'd expect a junior programmer to be able to answer any question solvable with Learning Perl, and probably to know some parts of Intermediate Perl, too' - what exactly determines whether knowledge I have, or anyone else for that matter is of a beginner, intermediate or advanced nature? what I may find or define as 'simple' may not be to others perhaps, I don't know, I might just be speculating?
