There's a fine line here...If i was a potential employer, and somehow figured out that you were blasting my company's career/job site, i would actually want to consider you speaking with you about the job. This is because I value resourcefulness, and also because - as part of the job interview - i would like to hear how you made the script; less the tech (though that's important) but more so the algorithm, your thinking on the script creation process, etc. However, if somehow you were to tell me that you did not develop the script, and merely used someone's else's script, than that would turn me off a bit. I would still applaud you for being resourceful, but you'd get way more points in my mind for creating your own. ;-)
