I spent the last 15 years recruiting.
Lots of good comment up thread.
Biggest mistake in cvs is length, and waffle.
Cv is a pitch for interview first, with about 30seconds life.
Later it may then be used in interview as a discussion stimulus.
The stuff you did 10 years ago is irrelevant, unless your most recent role failed.
Keep it brief, know what you are selling, and cut out adjectival or meaningless noise.
