I have taken the services of them many times, their system is that first they educate the candidate that their resume is good or not, if not they make it for you. And of course they charge for it.
If any candidate don't have good experience and education how he / she can think to have a very good job or interview calls. Theses gays only distribute the CV thats all their job done. Now it depend on your experience, quality of CV and negotiating skills to have job. Dont think u will pay some bugs and will get job regardless u have quality in yourself or not.
