I noticed a (relatively) high turnover of staff in a company that is known for seldom hiring and promoting from within. Specifically, In five years they've taken on three new sound designers. Only one has been promoted from within which, for this company, is unusual.
I stumbled across the 'skills-based cv' a few months ago when I was looking to present my work story in a different way. I was bored with the standard way of listing positions and duties, as that didn't really fit with the story I wanted to tell. In my view, a skill-based CV tells a potential employer far more about what kind of professional you are than a list of job titles and duties will do. For that reason, I think they give off a more professional air.
