This article really helped me with my resume, I already had a good rough draft but it made me aware of a few key things, like I had no idea that you basically only have 6 to 7 seconds to impress the person reading your CV.
6 to 7 seconds! WOW!
It made me realise I had to focus on the readability and make it eye catching. Maybe it might help you too, give it a read.
