I've worked for a CV/resume parsing company and had to talk to a lot of UK consultants (they would have stabbed me in the face if I called them the r-word). The vast majority are simply looking to fill positions as quickly and easily as possible, and don't give a jot about the candidates.
A couple of times, when I've been on the job markets, I've gotten calls and been told to change my CV to better match the massively-underpaid position they're looking to fill.
