That part definitely put me off too, but I wouldn't chalk it up to "trying too hard". I have a problem with the author's idea that putting "extra work" into a resume with animals on it actually made her a better candidate for the job in any way. It's worded as if she's surprised the song she recorded failed to actually demonstrate her competency to the hiring manager any better. Of course it didn't. No one hires software developers based on the colorfulness of their resumes or their vocal range.
