I have taken time to write this review. My CV was rewritten about 6 weeks ago and I was very excited to receive my very costly in ZAR terms, new and revised CV. I have subsequently applied for approximately 100 vacancies. Yes sometimes I was shooting with a shot gun or taking a chance with an application but many were accurate single shots. The result was 3 phone calls and not a single interview. I have also submitted the new CV to other companies for review and have not received a positive remark. So it seems that every CV review company only believes that theirs is good and all the others are not. I suppose that this is also a marketing opportunity to get the person to have their CV rewritten by the reviewing company for a fee.
One recruitment company said that my CV didn't have sufficient details so I sent them my "old" CV and they advised that it was much better as it was more detailed.
In closing, I suppose that CV's are of personal taste and what is one person or recruiters champagne is another's vinegar.
