Re: When was the last time you sexed up a CV?
Never did, as I never had to. When I changed careers from tech writing to IT, I put down my training and skills. Also sent a floppy with some small utilities I'd done and samples of a game I had in the works. I'm self taught along with having quite a bit of training in the first career as was the first person in the company to get a PC.
When I changed career path, I had two days of interviews and "tests". Managed to pass the interviews and tests although on a couple of the tests (writing utilities for querying the database) I had to ask questions which were points in my favor.
All in all, just be honest with the CV and don't be afraid to admit you're not sure or don't know but willing to learn. IT isn't static and a willingness to learn new tech, etc. is a big part of it.
