It seems that your example will filter candidates based on how much they like the company, not how good they are. The distribution of candidates will largely be the same or even worse, because a few good candidates may be put off by such rhetoric ("Why do I have to believe in local food systems, when they want me to write an Android app?"), but mediocre candidates will apply anyway.

So you still have to go through the same number of candidates until you can find a good one.
