CVs

Style over substance may be a common phrase but frequently CVs possess neither.

Layout

Inconsistencies make CVs difficult to scan read. Sure, it's not going to be a work of art (unless you're a designer of some sort, in which case it should be: show off your talents) but it should be set out neatly and consistently.

Fluff

Don't over-generalize. If you're applying for "Widget Developer" and you list "Widget development" under the responsibilities in your employment history, that doesn't tell anyone anything. Be more specific. Pick out some key aspects of what you worked on that are relevant. What impact did you have on the company you were working for?

Do yourself a favour, stand out from the crowd, and make it as easy as possible for people to see how good you are.
