On MSWord format vs PDF:
Whilst interviewing people, if I know their resume came via a recruiter, I tend to ask for their real one. The reason is not to cut the recruiter out of the process. Rather, it is to make sure the resume (and the questions about its content) are based on an unaltered version. Sadly, some recruiters will modify a resume to fit the position description, and the process, make claims on behalf of the candidate which are... untrue.
So, PDF, being more difficult to modify, seems safer.
