Basically jobs2careers is job search engine site like Indeed, Juju, simplyhired etc, they will provide traffic to other job sites. Because of these sites most of the jobseekers are confusing and not able upload their resume.
I don't know, however, how Jobs2Careers can be rated Excellent when the 'Excellent' rating is only at 69%. Reading the reviews, just shows how pathetic some people are giving 5 stars and they don't even know why. How do you give a site 5 stars when it list jobs that have nothing to do with what you are looking for.
In addition, Jobs2Careers also promotes work at home opportunities in the same manner they offer real, traditional employment. This can be problematic for a variety of reasons.
