I have never heard of this service before and did not read reviews before using the service.
I did free CV review and found it very informative and to the point. I was pleasantly surprised by the amount of helpful tips the reviewer provided me with. It made me realize how indeed ineffective and underselling my CV was. I also liked that my CV was passed through the scanning software that hiring managers use. I was shocked by the results and intend to rewrite my CV.
Thank you very much.
