While applying for work at Berry Plastics, I had to manually type in my cover letter. Most of the time the HR software lets you upload a Microsoft Word file. Interestingly, this HR software had a function to filter out “inappropriate” words, such as “red” and “man”:
I have no idea why these were “inappropriate” in themselves. More to the point, they also searched within words, so “ass” was flagged even though it was part of “assisted in”.
The upshot of this was to make the company and its HR department look stupid.
