I got my existing CV critiqued and reviewed by TopCV recently. I received a prompt review of it without 48 hours and it has been very helpful for me. I re-wrote my CV based on the points they mention in the review.
The reviewer analyzed the CV on the basis of overall appearance, formatting of text and use of language. It gave me feedback on how can I improve my chances against the automatic CV/resume analysis tools that are largely used by corporations to analyze these documents.
