I'm not happy with my results.
I don't feel that any incredible changes were made to my CV, only the structure was changed and a few things were reworded by replacing them with synonyms of what I had already written.
I don't feel any more confident about my CV than when I submitted it. Which is saddening, and it's been very time-consuming (and not exactly cheap for me as a South African).
DON'T DO IT!
