RE: The pros and cons of a functional resume
I disagree. I've had more success with a functional resume. Actually, it's a combination with the first page descibing my accomplishments and second and third describing my past work history, education, professional training, and associations.
And, as a manager, I disagree with your perception that hiring managers think candidates are hiding something with a functional resume. I do not think that at all. I carefully review the content rather than the format.
