When thinking through a possible FIT / PEI or cover letter response, most candidates settle on the first idea that comes to mind. Future edits of this idea do not alter the idea, but merely rearrange the wording. That is a bad idea. We use the so-what rule when testing candidates. For their responses we constantly ask “so-what” until the candidate arrives at the core reason for their decision / answer. That core reason is what we want candidates to use.
