I appreciate the thorough response. I guess we disagree about the purpose of a resume, I just think it is wrong to assess someone's worth off a one-pager(two pager max). There is obviously a lot of grey area between what a perfect resume and an atrocious one looks like, and that will vary even between each job application. Matching the expectations of candidates with those of the hiring managers is extremely difficult, dating can be thought of as a similar problem that has not found a great solution(and in no way am I saying dating is like interviewing).

For classification I meant that generally a company you have worked at will not be keen on you going around talking about their internal business needs, especially if it is close to the product.

Lastly, as some have mentioned, statements like 'increased this by X' are usually either fudged, or marginally related to what the candidate worked on, conflating factors being in the mix.
